Laughing man :

I think you are already doing that =) the settings does that.. I think the folder navigation will be for your specific media, so we will ignore other file types inside that folders...

But this is the kind of thing that we will avoid: We do know the importance of some features, but we will deliberated not attend all small issues... because if we do so, the whole idea and concept behind simplicity goes under water. "just add this.. and this and this" and you have a nice looking tree view that you cannot even see in which level you're and also.. a nice look hierarchical menu from the 80's on top of it =)

This will not happen =)

But again : if you configured you media folders.. your album art probably are not showing on photos today =)))
