Thanks Ron, I actually had a eureka moment after reading your reply here and on someone elses post. I think as I've always had 'edit local buttons' enabled, I hadn't realised I could just turn the pedals on/off via the editor, so seem to have solved that issue. I never had much joy with the touchpad scrolling down on OSX, though thinking about it, I think it's fine on my music PC, so can just do any future edits there for the more ridiculous IA buttons.
Hey Matt, I found an issue that affected scrolling the action list, and it's now fixed in 3.0.1.
