I have been digging in the settings and test editing the skin file too but I can't find anything about a few of the configurations I'm trying to make. I still have 3 things I want to accomplish:

1. No playlist number in title

I already disabled playlist numbering in the playlist, but that info still shows in the title bar.

2. Set playlist transparency

In D3d9 mode I was able to configure transparency and fade in/out animations on the title bar and the timeline, but I can't find any setting that will apply any of that to the docked playlist.

3. Change playlist font colour

I assume this one is probably controlled by the skin, though it looks like the skins use a strange x/y colour system and I'm not really sure what to do about that.
