This extension makes tab management super easy. I have had all my tab links disappear before, but they have always shown up again with a refresh or a browser restart. To be safe though, I do export my tabs occasionally.
I especially like:
- ability to name tab groups
- ability to lock tab groups
- ability to quickly reopen a tab group
- when my tabs get out of control, I send them all to OneTab where they are much easier to pick and choose the keepers and then sort them
The only thing that is mildly annoying for me is that I will occasionally hit the OneTab icon in my toolbar by mistake and send all my tabs to OneTab. This is a very minor inconvenience though because I can restore all the tabs almost as quickly.

it's great and I've been using it for years, but it is missing a merge function whereby i can merge a list with another one

it's a very good add-on, one tab is essential for me

Vital!!

Very nice!!! Can you make a button to sort by domain?
