If someone else already knows how to do this please let me know but how wonderful it would be if we could edit the overlays as separate layers (as in other video editing software) so that they can be turned on or off or even moved to a different area of the frame in a different clip. For instance, I like to use track overlay in my videos but don't want it to have to always be in the top right-hand corner of the frame for the entire video (all clips). For some clips, I may want it in the top left corner so that it isn't hiding features of interest in the video. Please continue to put resources into developing this application Garmin and don't pull out of this market, you could have a real good thing going here.
Also, it would be another handy feature to be able to merge clips together (the opposite of splitting).
