I got quite used to this in XCode. Is this something that could be added to AppCode? I'm not sure where the Mac app and the Java app meet and combine. As in, click on a different file/tab, two finger swipe takes you back to previous file.
I suppose to do it the way you folks to everything, which is completely and well, you'd want to add gesture hotkeys in your keymap settings. But I'd be ok with just the two finger left and right swipe being back and forward. :)
Is this the type of question that should just be filed straight as a request?
