This is a great extension. The main thing that was preventing me from moving over was tab groups!

Now the only thing I want is hiding tab groups that are not in use. Other than that its great!

It also super useful that this is also on Chrome. I have to use Chrome for work, so now I can have the same rules at work and home.

Thank You for this extension!

Edit: Also the dev is super responsive, he responded back to my review in 13 mins lol. Also it works for Zen Browser! I wish I could donate some money to the dev.
