Hey ,
Currently it is not possible to bind Buttons from your Mouse too your Ingame Actionbar and i would ask if it is possible to change that .
It would be a Huge Quality of Life change too have more easy usable Buttons.(as for example i am running out of keybinds on my warlock and using the F1-12 would be really painfull for my fingers because i have a rather Large Keyboard )
I cant think of any negative impact this change would have on the game , if anyone does find one please let me know.
Greetings
