Thoughtful extension with one major flaw. After using Sidebery for about a year, I would say it is really quite helpful in my daily workflow. Standout features include clicking on the current tab to switch to the next–most recent tab, tab panels for better organization, and a huge list of settings to customize its look and behavior.

The one major flaw is that in every panel except my main one, the tabs occasionally get shifted to the last panel with their order reversed. This is quite frustrating and partially defeats the purpose of having multiple panels. This occurs randomly every few weeks.

Tree style tabs convert. It works great, the only issue losing it one star is that it is tricky to see what tab you are on most of the time as it doesn't stand out enough.

The numbered vertical tabs were missing, Copilot tried to write the .css file, but wasn't very successful. ChatGPT gave up too... :( Will it be in the next version?

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
