I've gotten feedback from several folks that the current mechanism for selecting what to back up is cumbersome.
I'm thinking about changing it to a tree mirroring your computer's directory structure, with a checkbox next to each item, combined with a list of excludes that adds an overlay onto the tree of checkboxes. For instance, if you exclude items named "build", in the tree of checkboxes all the items named "build" would have a line through them.
So, instead of multiple folders showing up on the left side of the main window, there would only be 1. Likewise there would be 1 list of backup versions. If you select a backup version, you can view what was selected at that time for backup.
What's your opinion on this? Do you like the way it is now? Would you like a tree of checkboxes with excludes? Something else?
