If you have a a lot of open Tabs and you prefer working fast, you need to work with a Keyboard.
Closing Tabs with "Ctrl+W" and browsing/switching between tabs with "Ctrl+→" or "Ctrl+←" would be a small change but with a big benefit regarding easy of use. Or "Ctrl+1" for the first tab, "Ctrl+2" for the second,.... "Ctrl+9" for the last, the one on the right
Same Shortcuts as Browsers.
Easy and great benefit.
