Revamped filter actions

Revamped filter actions, i.e. the ability to do multiple filters, similar to the way focus behaves. For example first filter “John Coltrane”, second filter “live” returning all albums by John Coltrane with the word “live” in the title and maybe even a third filter “1963” returning all live albums by John Coltrane from 1963. I know that something similar can be accomplished by first doing a performer focus on “John Coltrane”, then a focus on year and then a filter on “live”, however the ability to do multiple filters would be much faster and simpler.
