Oh No! Pleeeease, don't put your affords in a new GUI system
If you want more eye-candy, improve the 3d-engine

For example:
- nice watereffects( dynamic water reflections ...)
- burning units ( movable ones / you can define them but ...... )
- black/dark shots ( black particels )
- working transparency in moving objects ( does not really work yet )
- animated trees? ( or does it need too much hardware?? )
