Then wait for the feedback to blow some horns.

That's what faders are for! It is often much more effective for novice users to address feedback by simply lowering the level than by trying to find the offending frequency(s).

I've not read the ops man in detail, but I think you could also set the level of the head amps below feeedback and then lock those which makes them act as limiter in a way. Anyone with M7 experience know?

I"m not positive, but I think you can secure it so only certain functions can be used (faders, scene recall, etc.)

If the gains are all set, you can throw a limiter on each channel (correct me if I'm wrong,) and lock that too.
