haha.. i guess i understand what u mean... that it'll be great if there's some tool to "compress" 16/32 bit colors into 256 colors...
however, here's the problem... when you try to squeeze 65k colors into 256 colors, you lose information, hence... kindda pointless....
BUT, nowadays technology quite advance, you can sort of manually "select" which colors you want in your 256 color palettes ... which would improve the GIF quality
