Your approach to work with a lot of windows?

Hi everybody!
I'm interested, how do you, <UnityDeveloper>, work with windows and popups in unity3d? What approaches, patterns and frameworks do you use, when number of windows is too lot? :roll:

 

I am just getting started but i picked up EZ GUI and so far its helped me get started developoing my GUI very fast. Maby this could you out.

If the number of windows is to high, than your application design perhaps isn't the best. Although I never had any performance problems with it. But I don't use GUI.Window anymore...

However, I use eDriven RIA framework (I'm the author). Check out the demo, multiple windows there:
