I'm creating a new blind (Stellar) with loads of animation throughout and wondering what program most people use to create/modify their .nwa files. Besides overall appearance with this blind, I'm concentrating on adding as many cool effects as possible. Right now, the userpane is fully animated with a 16 frame single .tga file although I'd like to expand the animation into the places menu as well as animating the wait logo. Pretty much all the buttons and other mouseover components do something so completing the start menu animations should put the icing on the cake.

Any feedback will be greatly appreciated.
