I'm pretty sure this one is on your roadmap somehow, but I cannot tell you the number of times I get asked about this one: people constantly want to be able to pull up a list of versions which just shows you the latest version per shot. Currently the only way they can do this is pull up a list of all versions, group by shot, and then order within group by date. What they really want is to say "Group by shot" and then only show the first result for each group, in a flattened out list view without the annoying group headers.
It's not just versions, either - we have scanned background plates for each shot, and sometimes they want to show the most recent scan per shot. You get the idea.
