It would be awesome to be able to execute PHP, esp. q2a methods from the admin panel.
E.g. I need to unsubscribe a user from the mass mailing, issue here, then I could just run a command in the "q2a console":
$loginuserid = 45;
qa_db_user_set_flag($loginuserid, QA_USER_FLAGS_NO_MAILINGS, true);
Instead I go through the database or even write another plugin.... :(
