At present, creating a new submission replaces the old one as the one you can view, but it would be nice to add the ability to view your past submissions, allowing you to see your progress towards a good solution. This could be in the form of a drop-down menu, and further features could even add the ability to play every submission (or a selection) back to back, or overlayed at the same time.
This would likely require a substantial redesign, and would not be a particularly easy feature to add, but would give a substantial amount of useful new features.
