please let's increase the precision of the timestamp when a file was scanned and added to the library.

Right now it shows yy-mm-dd hh:mm which is not sufficient in the following scenario:

• add a few new albums to your library folder

• start Mixxx, rescan library, sort by 'Date Added'
  = new tracks are grouped per folder (album), the track view is easy to read

• alter the tracks in view (change rating, delete tracks, ..)

• change to another library view, come back to Tracks
  = per-album grouping is screwed up
  = sort by 'Date Added' does NOT anymore group the tracks by folder (album)

A more precise timestamp would help here to easily restore the per-folder sorting.

agree with this. I would even be in favor of abusing the precise timing a little bit to our advantage: For tracks in a directory imported at the same time, set the timestamps and increase each file by one (one nanosecond or one nanosecond) for the alphabetical order of the files in the directory. That way sorting by date added would still maintain a predictable and useful order.

yeah, I also had the a-Z sorting in mind.
I thought this would happen automatically as files aren't recognised at light speed, are they :)

I have also asked this earlier, this will help much, when add many albums.

@owen Williams: It would be really nice if tracks with identical albums were inserted in reverse track-number order, rather than alphabetical. Reverse because this would allow sorting by newest-first date-added to also sort albums in the correct order.

Alphabetical is not necessarily useful, because even well named tracks are sometimes named e.g. artist - album 1 track.mp3, and this means that tracks 10-19 get inserted before track 2.

I would insert all files found at the same time alphabetically by:

• artist, then
• album, then
• reverse disc number, then
• reverse integer track number.
  And fallback on alphabetical by filename if none of those exist.
