I've always had a hard time looping samples. Yes, there is the cross-fade loop button, however, it never really turns out seamless. In Fasttracker II, there are loop markers that you can drag, which I think are very useful, and I really like. I don't like zooming to make a loop because I lose track of the amplitude from the loop start and end. If not, are there any audio editors that do this?

( P.S., Sorry about that previous, extremely useless "feature request". I stayed up kind of late to edit a few of my songs in OpenMPT :P )
