Just came up with 2 more things after playing around:
Music controls don't work on the lock screen - even when enabled for "When Playing" and when I use the Gingerbread theme not all of the apps that I had re-installed from TitaniumBackup aren't linked to the native apps in the Marketplace. When I switched the Nex Theme, they are all there. (It looks like the apps I paid for are showing, but any of hte free apps are gone). If I manually search for the app and find it in the list it shows up as installed but it doesn't display when I choose My Apps.
