Actually `git citool` is an alias for `git gui citool`.  Because the
former is much faster to type when you want to make a quick commit.

But this note is also really useful.  So maybe talking about the
longer form in the user manual is a good way to introduce git-gui.

Yes.  Now if only someone would teach it how to let you highlight a
section and stage/unstage just the selection.  Never mind splitting
a hunk.  Selection based stage/unstage would really be cool...
especially when combined with git-stash.  Where you could first
stash everything, reset back to the last committed state, then
selectively unstash changes into the working directory, test them,
stage everything for commit, then unstash more, etc...

Since git-stash is modeled as a commit, it could also work for
cherry-picking.  Which is very useful when cleaning up a series.
Hmm.  Wishlist for git-gui!

Yes.  Except git-gui (currently) destroys the author information
when it does an amend.  Bad git-gui!  Bad!  No prize for you!  :-)
