Hello,
When using foobar's album list I tend to use repeatedly the same filter criteria but I need to write the conditioning rules over and over again. How about adding to the filter box a drop down menu that allows to recall previous filter conditions ?
if you want that functionality now, you might consider looking at foo_facets as your media library viewer.
Alternatively you could create a few autoplaylists, which automatically update their content based on the pre-defined criteria. (Having a lot of them with a huge library might delay foobar's startup though.)
Thank you for the suggestions. I hope though this simple addition would be considered for future releases of foobar.
