OK, I set this up. It's pretty cool. Thanks for figuring out how.

But I wish it worked more like the Ion scratchpad. In that one, the
floating rectangle was permanent, and the hotkey just switched to it.
I'm trying to use the scratchpad to do 'vim ~/TODO' and it's a little
troublesome because the hotkey starts another one rather than just
causing the existing one appear.
