# SuperchargeNavigation 1.3.5 — Safer Sync, Gentler Workspaces & a Calmer First Run

> This one is about not losing things. Turning workspace sync off on one device no longer deletes the other device's copy, a device that can't read the remote stops writing instead of overwriting it, and local work that's still waiting to sync up is kept when the other device's data arrives. The automatic "Saved Tabs" backups stay on the machine that made them. The workspace model itself got gentler: "+" always opens a new window, saving a window removes nothing, and a switch that stops partway rolls back instead of leaving mixed state behind. The first open is just the Learn card now, and the rail that lives inside your page stopped being readable from that page.

## Highlights

- Turning sync off on one device no longer deletes the other device's workspaces — a device that can't read the remote now stops writing instead of overwriting it, and local work that's still waiting to go up is kept when the other device's data arrives
- "+" now always opens a new window, saving a window removes nothing, and a switch that stops partway rolls back instead of leaving mixed state behind
- Learn Nav is restructured into five blocks, led by six essentials that count your progress — and it remembers where you left off
- Auto-collapsing tab groups now ships off by default, and asks once in the panel after your first Alt+G grouping
- The first open now shows just the Learn card — the shortcuts card waits a day, and the sync card waits for a day and a workspace
- The in-page rail and the Alt+K palette are now shut off from the page they sit on — sites can't read your tabs or click them anymore

## Turning Sync Off No Longer Deletes Anything

Workspaces that live on more than one device used to be hostage to the flaky one: turning sync off on a device deleted the other device's copy, and a device that couldn't read the remote was free to overwrite it with whatever it had locally. Both paths are gone. Turning sync off now leaves the remote copy in place, and a push that can't read back what it wrote — or that finds data it never applied — stops instead of writing over anything. While such a push is stuck waiting to land — over quota, remote unreadable, throttled — the device keeps a pending mark, and any remote data that arrives in the meantime is merged with the local workspaces instead of replacing them: workspaces you created on this device in the meantime survive, and the mark clears the moment the write lands. The mark survives a background-worker restart, so a killed restart doesn't lose it. The automatic "Saved Tabs" backups a window switch makes stay on the machine that made them: they no longer ride into the sync payload, and the un-stamped ones 1.3.4 left behind aren't pruned on your first switch after upgrading. And if sync ever ends up in a state you can't untangle, the sync error state now has a reset button that clears local state and republishes from this machine, instead of you hunting for a way.

## A New Window, Not a Wipe

The "+" button used to set your window aside and clear it. Now it always opens a new window — even for a window that's already mapped in new-window mode — and "save this window as a workspace" stops removing anything: the tabs are captured into the workspace and the window is left alone. The first time an in-window switch would change a window's tabs, you get a one-time explanation with an "open in a new window instead" option, and a 60-second "back to Saved Tabs" chip gives you a way out. And a switch that stops partway now rolls back: it removes the tabs it created and re-maps the window to the block the tabs were saved into, so a workspace never ends up half-written.

## Learn Nav: Six Essentials in Five Blocks

Learn Nav used to be one long list. It's now five blocks with no switches at all — the options page is the only place you edit — and "Start here" is a list of six essentials that counts your progress, "n of 6", right in the block's heading and on the Learn button itself. The block remembers where you left off, so closing the panel or switching tabs doesn't send you back to the top, and it opens as a contents page now: all blocks collapsed, so you can see the shape of it before you dive in. When an essential teaches a key you haven't bound, the row strikes the key out in place and points at the settings card where it's bound. Behind it, the settings cards went from nine to seven, and the options page's Getting started card is now just the Learn pointer plus the four keys Nav ships with.

## The Rail Stopped Being Readable From the Page

The rail and the Alt+K palette sit inside the page you're browsing, which used to mean the page could reach them: a site could read your tab titles and workspaces, and it could click the rail the way you would. That's closed off now — the rail and palette are unreachable from page scripts, and events a page synthesizes no longer count, so a click meant for you has to come from you. The rail's calls to the tab API are also clamped to its own window, so they can't read tabs in other windows — they used to be able to read every tab in every window. And when the rail loses contact with its background worker, its calls time out after ten seconds with one quiet retry, and the rail shows a "lost contact — Reload" strip instead of hanging.

## Auto-Collapse Asks First, and Ships Off

When tab groups were on, Nav quietly collapsed the groups you weren't using — and it shipped that behavior on. It ships off now. And the first time you group tabs with Alt+G while it's off, the panel asks once — "collapse the groups you're not using?" with yes or no — one ask, in the panel, not a setting to dig for. If you already use it, nothing changes: profiles with prior use keep it on.

## Fixes & Other Changes

- Installing the extension no longer replaces your browser's new tab page. The custom new tab page is off until you turn on the toggle in the "New tab page" card on the options page, and while it's off your browser's own new tab page is used.
- The Alt+K command bar now lists open tabs by most recent use, so the tab you were just on comes first and pressing Enter switches back to it. The current tab is listed last.
- A pointer resting where the command bar opens no longer selects the row under it. The first result stays selected until you move the mouse or use arrow keys, and clicking a row still works.
- A web search started from the Alt+K command bar now opens the results directly in a new tab.
- The first open now shows just the Learn card. The keyboard-shortcuts card waits a day, and the sync card waits for a day and a workspace — and there's no "looking for your workspaces…" wait when sync is off.
- The rail also no longer loads favicons from Tailscale, CGNAT and LAN-suffix addresses — the 1.3.4 local-network favicon fix now catches hosts that only resolve privately.
- The mapped-workspace chip is hidden on the new tab page, so the current workspace no longer shows up twice.
- Tabs restored by a workspace switch or rewind now suspend right after they start loading instead of all loading at once — only the one you activated comes up.
- Arrow keys work again on pages that use a vertical scroll-snap pager, like Shorts-style pages — Nav yields the keys to the page's own pager instead of eating them.
- The "See it in the sidebar" button on the options page now opens Learn in the side panel — it used to do nothing.
- Hint mode no longer flashes capital letters at you: there's a short hold delay before a held key shows, a missed release self-heals, and a fast double-Esc resets hints, Glance, and the palette everywhere. There's also a hold-or-tap choice for the hint trigger key.
- "You already have this tab open" moved out of the page and into the sidebar, as a toast with Switch / Keep both — no more injected banner in the page itself.
- On Edge 150+, Glance's rule now applies to the tab you're previewing only. Previously it loosened the framing and content-security rules of framed pages on every site, not just the one being previewed.
- The sidebar renders one tab as one row: opening or closing a tab no longer repaints the whole tab list.
- "Restore default" on the new tab page is two clicks, with no confirm dialog.
- Background failures now all render through one error sink, and a stalled workspace switch gets a 120-second watchdog instead of hanging.
- The build is smaller — the public scripts are minified (about 466 KB where they were 906 KB) — and settings reads and host access are cached, so each tab pays for them once.
- Opening a workspace that's already open in another window now brings that window to the front (restoring it if it was minimised) instead of doing nothing visible.
- The sidebar rail's open/closed state (toggled with Alt+B) and its parked state are now kept per window, so toggling the rail in one window no longer changes other windows.
- The new workspace, smart group tabs, and ungroup all tabs shortcuts no longer fire on a paused site. You can still lift the pause from the toolbar icon, the sidebar pause button, the options page list, or Alt+Shift+P on the page.
- No new permissions.
