Although the developers did brag a little too much (oh well we all get excited anyway :D)... but when considering their approach (it seems like they've done a lot of research... talking to artists and stuff :) ) it may well be something especial. They're putting a lot of efforts into the UI design thus making it as efficient as possible still keeping the GUI quite simple.
Although it will take a little longer for them to release it officially but for those of you who just can't wait... you can have a sneak peak into the UI online through their official site!. Or if you're too lazy to play it all by your self, just watch the above and below ones instead :D.
But still this is the demo version and according to their own words...
"None of these are final, nor do they represent the limits of the Novacut editor"
