This may be a stretch but I'm going to ask anyways... Ability to use an animated gif on a MAT. With a simple 2x2plane we could develop some INCREDIABLE particle effects just by playing animated gifs via the Material file. As well as other stuff; computer monitors, cyberpunk billboards and numerous numerous other uses.
Or even better yet, avi / mp4 ..
** Yes this is probably already possible, but what a pain in the ***... you have to break the gif down to frames, recondition it in a 2d editor, save back out, build countless materials to host a single frame animations.. then develop an entire routine just to handle changing frames and timelines.
