I’ve changed the description a little.  The metaphor was a little too

I would write "Tree-based completion for Emacs", but I'm not sure if we
have a convention to mention "Emacs" in synopsis or description of emacs
packages.

I think this description is a bit too long, but I'm fine with it except
the last "\n", I would remove it :-)

I don't have comments on this package except for the same question about
mentioning "Emacs".  Maybe: "Quickly switch windows in Emacs"?

Since this is more a home of the source code, perhaps it would make
