Very unstable to manage a playlist

Tried 6 times to create a playlist.
No control over order of songs (unless you buy Pro which I find fairly expensive).
It feels like a soap bubble, as soon as you want to edit/delete one song, the whole playlist disappears, so you can start all over again.
I finally managed to get a playlist, but when testing, one of the songs didn’t work (even though the individual MP3 and Ogg were fine). Then again, no way of just editing that one song, as soon as you click “edit” or “delete” that single song, your whole playlist is gone again! So basically no control. Very frustrating!
I’ve given up in the end and removed the Plugin.
