This feature seems like a no brainer. I (and I'm sure many others) have multi-disc albums. I shouldn't have to name these albums differently in order to get them to sort properly. Currently in the web GUI and mobile app (DSub):
1. track name (from disc1).flac
1. track name (from disc2).flac
2. track name (from disc2).flac
2. track name (from disc1).flac
Can we please finally get a DISC column so we can sort by disc then track? I've been using this software for 7 years and I can't believe this isn't a feature yet.
