Please provide a save or export playiist option for further reference. like in case of reinstall of os or app so that playlist can be re-use
As a workaround, you can already move your data to other machines by copying library.sqlite from ~/.local/share/KDE/audiotube or ~/.var/app/org.kde.audiotube/
Maybe we could use a pseudo-m3u format, which contains youtube urls instead of direct links. At least some other media players would be able to handle them, like mpv.
I'm not sure if it's possible, but it would be really great to have the ability to sync playlists between KDE sessions, especially when someone uses Plasma mobile. Another feature I miss is the ability to import playlists from Youtube Music, Tidal, Spotify., etc Please let me know if you need help, I don't really have experience with C++, but I can learn if it helps.
