Grove — Persistent Tab Tree Manager 作者： GuoLiang

Stop rationing your tabs.

Most tab tools treat your open tabs as a problem to contain — prune them, suspend
them, feel guilty about the count. Grove starts from the opposite belief: your
tabs are worth keeping, and you should never have to choose between an open tab
and a calm mind.

Grove gives you a living outline of every window and tab, right in the Firefox
sidebar — and makes closing a tab completely safe. Close freely to reclaim
memory; nothing is ever lost. Everything you save, close, or restore stays in a
durable, searchable tree you can reorganize, rename, and return to anytime.

Nothing is lost
- Unlimited local storage — keep thousands of tabs and windows without hitting a wall.
- An automatic daily backup you can also export or re-import as JSON.
- On restart, reopened tabs re-bind to their place in your tree — positions, custom titles, and collapsed groups survive.

Everything is findable
- A live, nested outline of your windows and tabs that updates as you browse.
- Group, rename, drag-to-reorder, collapse/expand, and flatten nodes.
- Search the whole tree — including matches hidden inside collapsed groups.
- The sidebar scrolls to your active tab so you never lose your place.

Close without fear
- Close a kept tab and it greys out as restorable history — one click brings it back to the same spot, no duplicate.
- Reclaim RAM on demand without the anxiety of losing what you were reading.
- Full undo/redo of every outline edit — rename, move, group, delete, import.

Yours, and private
- Everything lives locally in your browser. Grove collects nothing and sends nothing anywhere.
- Configurable keyboard shortcuts, font zoom, and a browser shortcut to toggle the sidebar (default Ctrl+Shift+Y / ⌘⇧Y).

Grove is a clean-slate, open-source rewrite of the classic tree-style
tab-outliner idea, rebuilt small and fast in PureScript.
