[Feature req] VMU Swap
Many games only work with VMUs in specific slots (some only A1, some either A1 or A2), but obviously it's not possible to fit every save file into A1. With the actual Dreamcast, one could simply shuffle the VMUs around for different games to avoid this issue.
Within Redream the only option we have is moving individual save files in/out of a VMU. That has its uses, but it's less quick and efficient as simply swapping two VMUs. Technically, I believe this is possible to do manually by closing down Redream, swapping the filenames on the VMU bin files, and reopening Redream, but that's obviously not elegant at all.
With the real Dreamcast, the beauty of swapping the VMUs around was that one would develop a mind map of knowing where the save for a certain game was, and swapping is much faster and simpler than micromanaging save file export/import. Additionaly, the import/export feature is nice but not great for "quick" use, it doesn't ask for confirmation before deleting or overwriting those files. A single missclick could wipe out hundreds of gameplay hours.
Another suggestion that only makes sense if this one is implemented is: implement a tiny square icon next to each VMU, with, let's say, the "A", "B", "C" and "D" icons that VMUs could have in the real Dreamcast. That would make it a breeze to know which VMU has what and with the option to swap them around I think the overall usage of VMUs in Redream would receive quite the upgrade!
