This is great.. when it works. When it breaks Tab indents, it's impossible to fix.

Most important basic function is missing!
-indenting/outdenting tabs can only be done with drag/drop, and very inconsistant.
-when parent tab becomes independent you need to drag and drop each and every one below it back.
-NEED simple keyboard shorcut or option menu or UI shortcut (left/right arrow) to indent/outdent.





Stuff to fix
--indent and outdent current tab: need keyboard shortcut or context menu (drag and dropping is a bit too hit/miss)
-new tabs/"insert to the top of the tree, as the first child" doesn't work with Ctrl+T
-keyboard shortcuts are not modifiable
-some recovery issues with Tab Session Manager.
-but a bit unstable and Laggy after about 80+ tabs
nice to have!
-backup / restore settings?
