Feb 10th 2010 10:50AM Wanted to point out that your statement about viewports is a little misleading. A viewport addon doesn't create a black or textured area. It resizes the 3D view of the game. If you set up your viewport so the bottom part of your screen is black, it means that the 3D game engine is doing no work in this region. The important change is that where the game renders you character and surrounding elements on your screen shifts so that they are centered within your viewport, and not your monitor.
A viewport addon lets you have a UI that doesn't block out _any_ of the world view. KGpanels lets you wrap your UI in organized borders/panels.
