Me use steam; I just don't liek looking at the splash, but not a big deal at all, I could just change the splash screen to pure black, right?!
You might make the mapnames double-clickable if it's not too hard... I keep doubleclicking them, looking away to relax for a second, and noticing nothing happens! Or even a "start map" button.
"manually add commands and params, -dev -console "
Yeah, or even better do toggle switches for -sv_cheats 1 -dev, -console, or just automatically load them by default (what would it hurt).
