The only other feedback I have is that when you open Tabist and click on a tab, it'd be nice if you automatically close the tabist tab (and if possible to re-focus the previously active tab, which isn't necessarily the rightmost tab). Otherwise you end up with multiple windows with Tabist in focus.
This is fantastic though. I've been telling my friends about Tabist and everyone's saying how useful it is.
Awesome :D
Shoot me an email or add an issue on github if you think of anything that might be worth adding.
cheers!
