Vertical scroll bar and search needed in the Tabs Sidebar

[NotesTracker]

(medium priority)
I really like the tabs sidebar, but I usually have many tabs open and this necessitates lots of vertical scrolling. Please implement a vertical scroll bar in the sidebar like in the "List All Tabs" add-on.

Also implement a search function, like the search option in the "List All Tabs" add-on.

You may wonder why I'm asking for these two features in mainstream Waterfox when that add-on already has them. It's firstly because in the add-on as soon as you select one of the entries the add-on window closes, which os very irritating and time wasting. You really need to be able to pin the add-on window so that it stays open, just like you can with the Tabs Sidebar. Secondly, the search function is tremendously valuable if there dozens and dozens of tabs open in the main Waterfox window.

My apologies, but today I noticed that a vertical scroll bar already is implemented. The scroll bar is rather thin, so up till now it escaped my notice.

Still very much would like to be able to search for tabs (that contain the search string), extremely useful when you have lots of tabs.

Another useful feature would be to sort tabs (and unsort t hem), again just like the "List all tabs" add-on, which also is very handy.
