fine addon :)
The movable Tabs in the dropdown list and the mark of actual tab makes it my fav.

But you could copy following from:
TabSearch https://addons.mozilla.org/en-US/firefox/addon/tab_search/

- URL in the List beneath the title.
- Amount og tabs in the icon.
- Search also in the UR-Text.

thx :)

Is a hidden gem very useful.
