Tab Manager - sort, group and more

It would be perfect except when you select "auto-grouping > domain level > 3" it doesn't ignore the "www." So "www.google.com" and "google.com" are treated like different websites. The "www" is viewed as a third-level domain, so the tab group is named "www.google" instead of just "google." This also messes up alphabetical sorting.

SO GOOD!

Interesting extension. I hope you can add dark mode in the future. There is a problem when you (don't know you) already opened a new empty tab in another old window, And then in your current window, you enable autogroup, and then want to open a new tab in the current window. The new tab will disappear and get grouped with the empty tab in some random old window. This problem is not limited to the empty tab. My question is that I need a way to know (and follow) where the most recent tab is at when it get grouped into somewhere if it disappear from the current window. Maybe by a shortcut and/or a way to see the most recently open/visit tab in the extension?
