QoL for Katarina (and channeling ult in general)

Hi ! I want to know if i'm the only one that "double-tap" often channeling ult like . If i want to cancel my ult, i'll just move, not using R again. Maybe put an option for that ?

It happens (for me) so many times when i play Katarina, because it feel like that her QEWR isn't smooth as it should be : if done too quickly you don't proc the Q mark with EW (that's pretty stupid because Kat should be a quick char) and sometimes if you want to use you're R quickly after your basic combo you have to destroy your R key and just cancel it by double typing.
