I quite like how Ableton handles playback. 

If I press spacebar, it starts from where I last placed my cursor, or the last place I selected. 

So toggling spacebar multiple times lets me listen to something over and over, which is pretty much what you do with this program.

For the opposite behavior, if you want to continue from where you stop, you simply press shift-spacebar. 

I'd like to suggest that RipX adapt this behavior, or offer it as a choice in settings.

2:

If DAWs behave differently, users should be able to choose which behavior they like, from settings. 

RipX is a secondary program for a vast majority of users, even those who end up using it as primary tool probably came from another DAW.

So my second suggestion is:

If there's a bunch of these little UI things (say, keyboard shortcuts, behaviors gestures or whatever else), you might consider offering interface profiles modeled on expected behavior of different DAWs. 

This may be a bit of work, but even if you build it up over time, it should make RipX  a little less hard to use. And RipX is its own paradigm, at least up to a point, so I don't think we expect carbon copies of our apps, just the behaviors DAWs have in common.

It's a work in progress, we're all patient and happy, but we live in a world where we're drowning in a glut of affordable software tools, so lowering the learning curve is a great service to users, and happier users must help sales a bit, right?
