Ok I think I have simplified this to something that might be nicer.
Tuniac can now tell plugins these things about why a song changed:
-auto song change with focus
-auto song change without focus
-manual song change with focus
-manual song change without focus
Popup notify now has these options"
-always (all)
-always when no focus (auto and manual without focus)
-Auto song changes (auto with and without focus)
-Auto song changes no focus (auto without focus)
I would now say "Always when no focus" suits what you want.
Also because it was annoying me, double clicking plugins in the prefs window will now open its settings windows, if it has one..
