Seriously?
How about a fucking suggestions forum? Or are you too good to take suggestions from your mindless sheep-infested slavebase?
Anyway, on to my suggestion.
Is it so hard to fucking ask for a fucking change to the goddamn trade dialogue window? Like how about not having it RIGHT ON FUCKING TOP OF THE GODDAMN FUCKING MASTERY OR RUNE BUTTONS. HOLY FUCK WHAT A BRILLIANT FUCKING IDEA, I MUST BE SOME KIND OF SUPER GENIUS. HOLY FUCK.
