It seems that there is continuously being auto-created random bookmarks with the comment "Auto created by DSub". It seems unintended as I don't understand where they are coming from or what is triggering the bookmarks.
I think this bookmark marks your place in an audiobook, podcast or other music file over 10mins. If you restart playing, it restarts from that position.
Other than being confusing - is that a big issue?
The issue is that bookmarks are the only way I've found where I can make a note about tracks (either that I should add/remove them from a playlist in iTunes, give them 5 stars, or maybe change some meta-data). This is since there isn't an option to see a list of "starred" tracks or what tracks have been given a thumbs up or down.
The only issue is that I have to delete the auto generated bookmarks. Not a huge bug by any means, but thought I'd highlight it regardless.
