Currently, it seems to be impossible to add songs to a playlist from the files view (i.e., anything inside Library → Files) except by actually playing the song and adding it to a playlist using the “More actions” menu.
The three-dot context menus in Files should have the same actions as the context menus in, e.g., Songs or Albums.
Problem solved:
I want to be able to add songs to playlists from within the Files view. I want to use the Files view for that, specifically, because I have a bunch of songs that I wouldn’t easily find in other views as they aren’t in any albums.
Brought benefits:
If the context menu for songs would be the same everywhere, this would reduce confusion and thus increase UX. The way it is (and I assume it’s because of technical limitations / not having all the required metadata when opening a folder), it feels kind of unpredictable when the functions I need will be available and when they won’t.
Okay, I see, that makes sense. I understand if this is not going to be implemented.
However, Emby seems to support this without limitations on the web UI – I can even add whole folders to a playlist. Except… I suppose adding something to a playlist on the Emby server is different to adding it to a local Symfonium playlist (which I could sync to the server), so I’m assuming the difficulty lies there?
Anyway, because you mentioned it: I can’t really easily find my media in library mode because it’s more or less random songs, and the only thing they have in common is the folder I’m storing them in. But I think I can work around this by creating the playlist directly on Emby and syncing it over to Symfonium.
