I've added a new key to gtetrinet, bound to backtick by default, to use the current special on yourself regardless of your player number. I've also added options to raise the gtetrinet window when a game starts or finishes, so you can go do other things after you die and not miss the next game.

I sent these changes to the gtetrinet maintainers but got no response, so I'm giving my version a home here. You can download the source here; here is a binary (as a .deb package). Let me know if you have problems with either.
