voting for changing ctrl+# ... personally i have never used more than 2 trays. on the other hand i almost always use the shift+# to pick teammates (and yes, i am definitely appreciative of you adding numbers by their names)
btw, while i'm here, is there any way you make it so i can see my own info just like i do on other people? maybe its just me but i like to be able to just see a nice page with all the badges and powers showing (rather than having to page thru 5 different lists)
