Hmm...I have to disagree with Inverness for this reason:

When I create a GUI window I'm only going to be placing controls in a space once. After that it's done, so I don't see the need for having every control placed relative to another control unless you're going to have to do a lot of re-arranging later on. The way I see it once a GUI is designed, that should be that.

Also, I just tend to be able to design better looking GUIs by seeing what they look like in real time instead of having to update every time I make a change. The lack of controls on the GUI editor is a bummer in my opinion also, though.
