I would like to see a better way to edit the lip sync line, perhaps a pop-up screen that gives a bigger picture. Those little itty-bitty phoneme tags against that little itty-bitty wave file, are a bit difficult to sinc up. It's kind of hard on the eyes and patience to be messing with these little icons for hours at a time in front of a computer screen ... it makes for a long day of animation.
Crazy Talk 5 is designed pretty much for the amateur, home user, but it has so many professional and commercial potentialities, than it really needs to address this level a bit more.
