About TreeSide - Vertical Tabs in Chrome's Side Panel
TreeSide puts your open tabs in a vertical tree in Chrome's side panel, so a deep research session stays readable instead of collapsing into a row of unreadable favicons.
Open the side panel and every tab becomes a labeled row you can actually read. Open a link from a page and it nests under its parent as a child branch, so the path you took through a topic stays visible. Collapse a branch to fold away a finished sub-thread; expand it again when you come back to it.
WHAT YOU CAN DO
- Drag any tab to reparent it, or pull it out to the top level, and the tree reshapes instantly.
- Collapse and expand branches to hide or reveal whole sub-trees of tabs.
- Fuzzy-search every open tab by title or URL and jump straight to the one you mean.
- Group related tabs and name the group; the grouping stays put in the tree.
PRIVATE BY DESIGN
TreeSide runs entirely in your browser. It reads only your own open tabs to draw the tree. There is no page-content reading, no browsing-history upload, no account, and no tracking, and nothing leaves your device. It requests only the tabs, tabGroups, sidePanel, and storage permissions it needs to build and remember your tree.
WHY A TREE, NOT A FLAT LIST
A flat list of tabs still loses the structure of how you got somewhere. A tree keeps the parent-child context, so a ten-tab research dive reads like an outline instead of a pile. Close a branch and you close the whole sub-thread with it, in one move.
