>>Actually, you can add new methods to contained objects, via a builder. Like this - select a contained object first in the designer, and type this in the command window:

aSelobj(a)

I've tried this before, and the extra methods in the contained objects were just gone. Probably when the class (or form) is compiled.

It is, but it's the remaining 10% that makes this unusable.
