My first problem is with Foobar deleting playlists. I found a forum post on google about this and it says to go to preferences - > core... this is where I get lost. Preferences for my Foobar has no core option. There's components, display, keyboart shortcuts etc. but absolutely no core.
Then there's the fact that foobar doesn't budge when I download and "install" a theme. A confirmation box appears in foobar asking what parts of the theme I want, I click ok and nothing happens.
