What do you mean by filter? The Allow and Deny filters can be dynamic or static playlists.
If what you mean is to be able define dynamic playlist with a rule saying that the song is in another (static or dynamic) playlist, I suggested that some time ago, but anonbeat said that it would bring performance problems. And you also would need to check for circularities in definitions, which makes things more complicated.

I also think it would be a nice feature, but I'm willing to give it up if it will hurt performance.
With that feature you would need to do a query of a query (of a query ....), which can be problematic on large databases.

And what about adding multiple filter to the player filter like "allow X and Y Deny Z and W" instead of only one?

I don't know about that. Another restriction is that you can join all the rules by AND (default) or by OR (ticking on any criteria). I don't know if it just because it simplifies the interface or it is also for efficiency reasons (I guess it's a bit of both).

With your suggestion you would be able to overcome the restriction, but maybe that's not wanted.
