Thought bubble z-order.

[KodiakBehr]

I'm working on a game with considerable amounts of dialog that would better fit as a thought bubble.

Now, I know Resonance does this well, and I have no idea how, but I'm going to assume that it's way out of my league.  I'm trying to use the system that is already implemented.  At best, I seem to be able to get a basic balloon (that has no cloudy properties associated with it) as a text window GUI and a small set of circles that lead from the character's head to that balloon.  Those circles would ideally that a higher z-order priority than the text window GUI, but I can't seem to make that happen.  So my questions are two-fold:

1.  Is there a way to change the Z-order of a text window GUI?
2.  Is there a smarter way to implement thought bubbles that I'm missing?

Thanks!
