We need to do everything we can to make sure that people can find their loop points easier. In lieu of beat or onset matching, scrubbing would go a long way to help people fine-tune the sliders. I can't think of the specific example, but there are a couple of audio players out there that would loop a half-a-second or one-second segment of the track while hovering over a spot with the mouse depressed.
In our case, I should get feedback when I'm sliding our UISliders in addition to the tooltips that are already in development.
Ah, just saw this. You've nailed my thinking from the two I just posted.
