Hi Magnus,
yes, it is indeed a very complex plugin, and it might not be trivial to
get the note functionality out (I tried, but couldn't find an easy way).
So my reccomendation would be
to just disable all the other tabs that you don't want to have in the
MagicTabs dashboard. That way you will only see the tabs that you want
and need. (For example your note tab)
