I have collected several ideas after thinking some time about the autoplaylist manager: Nothing really great but in the summary they could make foo_autoplaylist an universal tool for creating/managing playlists and searching. Here they are:
1. Creating a autoplaylist inside autoplaylist manager shouldn't create automatically a autoplaylist inside foobar. Nicer would be to have a list of presets from where autoplaylists can be created inside foobar. So once created you can delete autoplaylists without creating them again in autoplaylist manager because you have the presets. So you can display just what you need in moment
2. Not only autoplaylists but also normal (editable) playlists can be created.
3. -If some form of limitation should be introduced (fe: limit by 100 tracks) it would make sense to differentiate between population sort and display sort order.
-Great would be to have other opportunities of limitation: fe. Limit (Genre=4|Artist=3|Album=1|Title=2) what would mean: "just 4 genres, from each genre 3 artists, from each artist 1 album and from each album 1 track"
4. A be better way to create queries concerning timestamps (Last played,...)
Thanks for attention!
