A way to exclude genre/type/source from media list

[donpaul]

Would be nice to be able to exclude a genre/type/source from view in media. Currently if there are 12 genre, and I want to see all but 1, I have to click the 11 I want. There should also be a way to select for exclusion. Maybe click once to only view that genre (button turns blue), click again to exclude (button turn red). Not sure if it is possible, but would make browsing media a lot easier.

Another scenario where this may be useful. I have some movies tagged as both fantasy and cartoon, or both action and cartoon. What if I want to see all fantasy and action, but no cartoon. Can't do that currently. Makes it difficult no navigate media.
