Sorry, my bad. I did look through the settings but I somehow missed that option. Thank you!

I apologize for necroposting in this thread, but I am new to Spine and using the RMB instead of MMB to pan has felt really awkward for me. I suppose that I might get use to it in time but I hope you really consider letting us swap the RMB and MMB functions.

Personally I find it much more comfortable to pan with MMB and in pretty much all other software that I use the panning is done by MMB or Space + LMB. Please consider it!
