I have an idea for a feature that can analyze a playlist to find ERRors and possibly find duplicate entries.
When you play through a list and encounter a file that no longer exists or was renamed it marks it as an error in the playlist viewer. This is handy so you can update the playlist with the file's new location or new name. It would be nice to have a function that could go through the entire playlist and verify there are no errors and if it finds some, mark them. Sometimes my playlists become obsolete because I'll do some housekeeping of my music files and rename them or move them around. That's when I get ERR in my playlists. Would be nice to have an easy way to clean them up.
I'm always adding songs to playlists and once a playlist gets large I unintentionally add duplicates. It's not a big deal, but it would be nice if there were a function that would show me duplicate entries in a given playlist and give me an option of deleting the 2nd entry.
These are just a few things I thought of. Maybe if someone is bored they could tackle these functions...
