What is the perfect tab manager feature? Tell me before BetterTabs launches

Hi, I'm Rohit. I'm launching BetterTabs, a tab manager in Chrome's side panel, and before I do I want to ask you one thing: what is the perfect tab manager feature?

If you already have a tab manager you like, you don't need to reply. If you're curious, try BetterTabs and see what it does that Chrome's tab strip doesn't. It's free, open source and has no account.

The features I think matter most, in two or three words each:

• Side panel list: beside your page

• Group by site: one folder each

• Four views: your way

• Search: tabs and history

• Rename tabs: your own names

• Close duplicates: one click

• Favourites: pages or sites

• Saved lists: reopen later

• Backup file: restore anywhere

• Select several: act together

• Suspend tabs: free memory

• Back and forward: between tabs

• Status bar: memory, CPU, tabs

• Private: no account

The screenshots show the next version (1.8), which adds back and forward between tabs and the status bar. The Chrome Web Store has 1.7.1 today.

What's planned, also on the roadmap at bettertabs.fyi:

• Next: drag and drop between windows, closing idle tabs automatically, Edge and Brave.

• Later: workspaces, notes on tabs, a duplicate warning, a tree view.

• Not planned: syncing between devices, because your tab list would have to leave your computer.

My question: if you could add one feature to any tab manager, what would make it perfect? A few I'm weighing:

• Snooze a tab until tomorrow

• Workspaces for work, a trip or a project

• A note on each tab for why you opened it

• Closing idle tabs for you, with undo

Which would you use most, and what's missing from this list? Try it at https://bettertabs.fyi and tell me what you'd change.
