When in Files (in sidebar) I right-click a directory and choose one of the three playlist options I get what I expect, but also m3u-files are loaded/added to the playlist. When Strawberry encounters the m3u file it stops playing and says "This appears to be a text file." Not sure if a playlist could refer to other playlists but since Strawberry doesn't seem to handle them would it be better to not include them in the first place?
