Would the ability to surround transparent sprites with outlines be a feature anyone is interested in? I find it effective for adding contrast to the edges of HUD elements. Here's a short video to demonstrate it:
http://www.youtube.com/watch?v=SawXmTYuAlkI implemented some code changes in NGUI that basically duplicate the way UILabels work, where you choose an Effect from the drop-down menu (Outline) then specify color and x/y distance. ArenMook didn't respond to my private message, but I imagine he probably gets trillions of those a day, so no worries. Consider this a feature request!
I am mainly hoping to avoid needing to re-implement my changes each major release. Does anyone think feature may be useful?
