Hi, I m a newbie with ngui, and I am using the free edition to check if it fits my needs for a project I want to make, and if so, to buy it.
So far, I have made a drag & drop scenario using my custom scripts and widget buttons with the sci-fi atlas, and it works really cool.

Its important for the dragged object, when dragged to be in front of everything else on screen. Maybe its a lame question but how do I do that? Can I change the depth value by code? The dragged objects are buttons consisting by a label and background. Changing the z value didn't work. Do I have to use 3d camera? Please give me the most optimized solution.
Thanks
