Automatic beat, downbeat and onset detection is on our roadmap, too - not just for adjusting the paragraph width, but also for placing markers and dropping the playhead so that it doesn't cut the onset. It's actually not trivial to implement a good beat tracker for these "loose" recording scenarios - you might fluctuate in your tempo, start and stop again without pausing the recording process, etc.. We won't ship it this year, but I promise it's high on our priority list for next year :).
