I'm thinking my second idea of letting us create a custom property editor
window that could return any type required would be a lot more useful than
just making Integer[] Float[] also work in the form designer.
Possibly even less code as you'd just have to check for () in the
_Properties def "*, MyPropertyName{type_is_method()}" then set the property
edit button in the IDE to run the method and pass it's return data straight
to the property.

Hmm, When i put it that way it does sound like a fairly simple addition.  I
might just have a browse through the IDE code and see if i can find the way.
