Animation Studio (harmonizer)

@Alex: I'm not 100% sure this is a bug but could you please sort out the animation studio so that it only moves the character on left click & drag when set character center is enabled?

Currently it sets new character center on left click as well which is quite annoying as you might accidentally left click on the window somewhere by accident (touchpad can be sensitive sometimes) or you might have lost focus to the window & just want to set focus again so you can nudge the character a little bit with the arrow keys & instead you end up moving the character to a completely new location.
