Just to add to this.... Your 1st question as Brad said, no not at the moment, but that's a good bitbucket request feel free. 2nd Question, if you just decided to "HIDE" your roms, then that is all they are hidden, but still available. If you decided to re-import (which sounds like you are edging towards) then everything will re-import, but you can specify a different import process. (For example only originals, originals and clones..etc...) 3rd question, just use the "Scan for added Roms" which is under the tools menu.
