fast, easy, should be a basic thing, thanks so much for this!

One of the few addons that works with Pinned tab groups.
Allows Load/Hide/Switch of Pinned Tab Groups.

Works great with Simple Tab Groups (STB) to manage load/save/switch tab groups (STB doesn't load/hide pinned tabs).

Doesn't save which container the tabs are in. Always loads tabs in default container.

Works as expected. I do not understand why this isn't standard in any browser. Thank you!
