This one is a little frustrating, so I figured it would be a good feature request: when a loop is set, logically the playhead should start playing back at the start of that loop.
Currently, setting a loop is a two-step process: set the loop, then set the playhead at the start of the loop.
If there is a reason this functionality exists as it is, I would love to hear how it's useful. Otherwise, in my humble opinion, it should be improved.
