Why isn't the designer layout included in Generate Members?

The designer does not know if this is the main layout for the activity or an overlay for other use. You may also load it into a panel, etc. Layouts can be loaded at anytime in the activity. The majority of layouts I create are not loaded in the activity_create, however the variables have to be there no matter where the activity is loaded from.

I'd like to have them created as suggested then I would move them where I want them.
