So since there was never any official thread, here goes. I am working on a complete different API and user interface that should change the viewer quite a lot (hopefully for good). The new API should make it easy to load multiple models, move them around in any way you want, change textures on run-time (e.g. to test custom textures) and attach models to other models or nodes (e.g. attachments). In addition, there will be no distinction between Warcaraft 3 and Starcraft 2 models, you will be able to use both of them interchangeably. The new user interface would be a fullscreen menu that can be opened or closed via a button or key shortcut. If you have any suggestions as to how it should look, go for it, I am no designer or artist. The menu will be context-based. If you have multiple models, you will be able to select one and the menu will change accordingly to reflect that model. The animation speed is going to be removed, since it's a useless and buggy feature. Software rendering and one of the hardware rendering modes are going to be removed. This means the viewer might not work for some people with really terrible computers for which it currently does work, but the numbers should be quite small. If in the future I see that this affects many people, they can be re-added.
