The GUI needs to make it obvious and clear which game you're configuring in these places:
[x] Settings (could also hide the MUA specific UI settings for XML2 - and possibly move a few settings to this tab, which don't need to be as accessible)
[x] Teams
[x] Skin editor and installer
The last two items can be in a hierarchical manner in the navigation pane.
[x] Only slightly related: To clarify what the selected characters are, it could use a header
