I'm just testing some of the cvars listed, but so far the most useful one for server admins seems to be:
set ui_minicon 1
Which displays a transparent copy of the console on the game window whenever a message is displayed on it. So I've done a
bind PGUP rcon status
and I can see the clients listing without bringing up the main console window (which is useful if you have some reserved spots on your server so that you can check which players are using them, and for using clientkick in a faster way).
Sorry, I think I don't understand you ed: ... By having the variables set up that way you press pgup, then a rcon status is issued, and you can see the results on the game screen, without having to bring up the console, that's all...
