thank you

Unlike TST; Handles tab groups and tab colour. Panels adds another level of organization.

Lost a star for: 1) Not providing for increased indent on child tabs (group tab colour, inherited by child tabs serves the same visual purpose; which doesn't apply when you are actively accessing children of multiple search tabs) [settings, style editor, tabs, indent=25,on]. 2) The inability to show bookmarks at the same time ala TST. (but there is an icon {bottom middle} to bring up a book mark sub-panel).

Not as good as Simple Tab Groups, but it's an alternative.

Please add a function to force update favicons for all bookmarks.

Is great with few bugs that if fixed would make it a 5 star.
Bugs:
Tabs merge with other panels sometimes
Shortcuts don't work when sidebar is not displayed
One of my panels lost all tabs once
Moving group to new window causes tabs to fall out of group
Extra Features:
Make snapshots more usable allowing you to rename them, remove and add tabs, organize them, restore or take snapshot of a selection, etc.

Clicking the Add button when all tabs are cleared does not add tabs properly.

Nice! Thanks!

it's a great add-on but I'm having a problem with it.
It doesn't work properly with browser.tabs.closeWindowWithLastTab firefox preference.
I have to deactivate it first.

Please implement

Automatic groups, for example by domain

To close tabs when selecting multiple

Ability to place a new tab button in the top bar

And show an interactive animation line at the bottom of the tabs when loading

Takes some tinkering and getting used to, but helped my quitting my addiction to Arc Browser. Should inform users that you must take snapshots if you want to keep your tabs

good tree better than the firefox one
