I believe I understand the issue, since I was looking for the same thing.
Whenever you will start a new video, the playlist will "disappear", and you have to turn it ON again (CTRL+L/toggle button). It is annoying.
Go to Preferences, in the main Interface section, look for option group Playlist and instances.
I had check this 2 options:
- Allow only one instance
- Enqueue items into playlist in one instance mode
This seems to solve the problem a bit.
What are the results?
If I will play something, the playlist will not disappear anymore. However if I will go to fullscreen mode and go back to window mode, the playlist will vanish.
If I will stay in window mode, and go on to play whatever I want, it is ok, and stays OK. But once I will close VLC Player, and open it again, open something (video file), again, the playlist will vanish, but after I turn playlist ON again, it will stay. So results I get is:
- open playlist with videos songs etc.
- start to play (my playlist will hide)
- turn ON the playlist (so you can see it)
- and that is it; STAY IN THE WINDOW MODE
This steps I need to repeat each time I will close VLC Media Player.
It is a little bit less annoying, but still bit problematic.
Additional note:
Somewhere else I had read, that this issue is from 2012 (!)
and it will be fix with a new GUI of 4.0
When that will happen? Not sure...
I had test this with VLC Portable version 3.0.18
Hope this helps.
