Ideas¶

General features¶

When running import check/fix, don't change source files (configurable? 1. fix in-place, 2. use temp dir 3. copy to library, then fix)
Select/filter albums based on stream info, recent access, etc
Support additional file formats
Dynamic collections e.g. by field value or partial path
Option to use ID3 2.3 instead of 2.4 (if people still do that?)
Improve Unicode support (e.g. case insensitive comparisons)
Localize interface (per volunteer)

more genre features
- limit genres to user-defined list
- guess genre w/ albums from same artist (in library, not from import scan)
- save mappings from any-genre to user-genres
- use $genre in path templates
read album comment tags (various) and add per-album check(s)
scan date(s), require/special validate, use in file/folder name templates
support new field checks for composer, lyricist (and their aliases) to address possible split-albums
restore the preview option to review automatic fixes without running them. Note that doing this accurately requires simulating the automatic fixes in a way that lets the checkers re-run, exposing additional automatic checks or in corner cases allowing other checks without automatic fixes to fail against the result of a simulated automatic fix.
many suggested fixes for current no-fix check failures in TODOs
low bitrate or suboptimal codec
not all tracks encoded the same (file type or bitrate target)
parent folder doesn't match artist if using artist/album
automatic visual similarity check for front cover art, so it can be stored in multiple formats and resolutions without disabling uniqueness check
repair combined tracknumber/tracktotal and discnumber/disctotal in FLAC/Ogg

speed up first scan/reread with worker threads reading file metadata (mutagen + picture scan) into plain data, applied to the ORM by the main thread (sessions aren't thread-safe); est. 3-4x on the file-reading phase
