mbnuqw, thank you. I appreciate you making this extension. It has been an amazingly powerful tool for my work.

Pin tabs are not saved.

I used Simple Tab but now it seems outdated. Sidebery gave me the Simple Tab-like functions I was looking for, but also way more! And it looks great! If you want to have workspaces that are easy to sync with other devices ( through your cloud of choice) in json and markdown, this is an excellent extension!

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

I can finally leave Vivaldi for good

Rotding brengt alles in de war, waarom de systemtray, hoe raak ik dat kwijt, config is een jungle.

TST but way better, with more customization
