Script that gives you 1 button to swap between kritz and uber, and another button to swap spawns (by changing loadout). Also spams "kritz used" or "uber used" depending on which you're using (as opposed to "kritz or uber used").
In the script the 'medigun' alias is used, which is an alias I use for crosshair stuff, like so:
alias medigun "slot2;cl_crosshair_red 32;cl_crosshair_green 192;cl_crosshair_blue 32;r_drawviewmodel 1"
