STAR ratings for videos

Hello again - equally absent, the ability to RATE a video when seeing it.

I understand that this may be more difficult to implement.
Besides, it gets somehow mixed up with the existing ratings concept (which is the actual “official” ratings for movies / series, such as IMDB and such). It also collides with the “favourites” system for choosing network shares (which is actually a redundant function).
However, I’d really REALLY like to be able to rate videos with my own rating, or at least easily star / mark them, to go back to those when I want to.

For the moment, a stop-gap solution is to create a playlist of “favourites”, and keep on adding stuff to that. However, this does not seem to work when doing a shuffle play. Why is this not possible?

Thanks in advance for getting this in !!
