Non-Music file support - what should I expect?

I use a lot of Audio books in FLAC and MP3 recorded from cassette. I also have DAB radio grabs (MP2 that I convert to FLAC) I record these 0ff air to an SD card via my ‘Pure’ DAB radio (Currently collecting Paul Temple and The Gregory Affair)
I update the file data before importing and it all works a treat. I tag the ‘Audiobooks’ and can quickly focus on them or exclude them. I add my own cover art as I go and have some standard cover art for one off plays.
I also put them under Audiobooks in my main folder.
