Hi! 
Just subscribed and was very excited about getting started, but unfortunately the editor is pretty much useless to me since I haven’t been able to invert mouse y-axis for its navigation.
Couldn’t navigate my way out of a paper bag if my life depended on it without inverted mouse control. 
Searched the settings but couldn’t find where to invert the mouse, so any help/info on this would be greatly appreciated.
EDIT: For clarification: I want to invert mouse y-axis for the viewport navigation specifically, and I’m not referring to “Invert Middle Mouse Pan”.
Thanks in advance!
Cheers
