Certain files (like an email file for Outlook, Thunderbird, etc) can accumulate a very large number of versions over time. It would be nice if there was a user interface to allow you to go remove some of your old versions (my Thunderbird mail folder file is something like 200MB and I have now like 80 versions of the file, so it's taking up an excessive amount of space in my Cucku archive).

I see maybe 3 parts to this feature - one would be to allow me to select individual files in the Archive, and delete individual versions from the history. The second would be to allow me to select an individual file in the Archive, and tell it to delete all versions older than a specified version, or older than a specified date/time. Finally, there should be a couple 'global' options to delete all versions older than a certain date/time, or delete all but the last X versions of every file (maybe I just want to preserve the last 5 versions of every file).
