Hi @elan, in December '20 you wrote the following in the Plexamp 3.4 release notes:
The most notable addition is the powerful new library filtering/playlist builder. We hope you enjoy using it as much as we enjoying building it. (And don’t worry, smart playlist editing/deleting is coming soon as well, we just couldn’t wait to get this out for you to play with before the end of the year.)
Can you shed a light on when we can expect this feature? It’s been a while and while I love the smart playlist feature, I use it a lot less than I would because I have to recreate complex smart playlists too many times to get them right.
