I have a feature suggestion:
An easy and quick way to filter the list on encoding types (filename extensions, .mp3, .ogg, .wma, .flac, .m4a, etc).
Right now, I use filtering on \_PATH, but it is not simple (I have to type the extension every time I want to change it--I would prefer a toggle or action) and I cannot combine it with other filters (e.g. filtering on %artist% at the same time).

You may try to filter e. g. mp3 files:
Field: **\_FILENAME**
Filter: **.mp3$**
A combination of sorting and filtering may give proper sets of files to work on.
