Here's one that I remember asking for.

The DataEnvironment, Grid, PageFrame, Command Group and Options Group base classes all include an Objects Collection. This is very handy, so whever you want to scroll through all levels of controls in a form, you don't need code like:

do case
	case loControl.BaseClass = 'Option Group'
		for each loButton in loControl.Buttons
			...
		endfor
	case  loControl.BaseClass = 'PageFrame'
		for each loPage in loControl.Pages
			...
		endfor
	case ect. ect.
endcase

Just one for each oOPbject int loObject.Objects. Its also great to have this in the DataEnvironment, so we can whip through the objects without having to do an AMembers() or some work around.
