I just wish we could pick a dominant video and choose other video lengths and music lengths based on time and desired timing. A lot of time is wasted on trial and error trying to get things to line up the way I want them to... Then I find that the video is a little too long for the song clip with an awkward ending. I work through these things or give up. Just depends on how much time I have. Otherwise this app is very, very good!
