Just encountered a minor thing that might be worth looking at.  Tested it on the Jan 8 Nightly.  
If I have a movie with two versions, A [default] and B, and I remove one of the files from storage and clean my library, here's what happens:
If B is removed, the listing for A works as expected and is treated as a movie with no alternate versions.
If A is removed, the listing is removed entirely.  I can then re-scan my library and B will be added back in.

So my question is, should this behavior change?  If the default version of a movie is removed and the library cleaned, should the listing disappear entirely?  Or should one of the other versions present be chosen to be the new default. Maybe just arbitrarily pick one for the sake of keeping the library listing and the user can specify if they want to change it on their own later.

When there's only two versions, it's not really an issue, but if someone has like five versions of a movie and removes only the default version and cleans their library, they then have to re-do the versioning for what's left as it is now.

I guess you should really be using the versions manager first so you can change the default version before removing it from your storage.

Yeah, that's probably good practice.  I honestly see it as an edge case scenario.  I just did it because I was messing around with stuff on my test install and noticed the behavior.  I don't really see it being an issue for me during normal use, but I could see it popping up for some users going forward.
