Sure, tooltips are just one thing that can make things easier to use...

I am not aware of an easy way to do that.  Creating a vc-git-dir-mode
derived from vc-dir-mode would help...

How about adding buttons on the Stash line:

Stash   : Nothing sashed     CREATE STASH     STASH SNAPSHOT

That would make it more obvious how to create a stash.
These are not very frequent actions, so it would help not having to
remember a key binding.

There's some difficulty with the buttons: the "Stash:" is inserted as
a string in the EWOC, and the widget.el buttons want to be inserted
using widget-create (or somesuch), so the buttons might need to be
created from scratch...
