you're kidding or you're joking? just look at your product and Anastasiy's. it's like trying to redraw some famous portrait and asking "what? i've just drawn a woman, nothing new". i'm not the first and i'm not the only who say you about that. just look up this thread. what do you copy next? blur filter? why don't you make some original product that does some sophisticated color conversion or layer management - something that is really needed?
The fuck centauro, Its a colour wheel! with your reasoning you can say, that Anastasiy copied the painter colourwheel. A docked colourwheel is very much needed, and the more plugins that provide this feature the better. (the customer can pick and choose which one they like best).
Totally agree, if this was implemented it would definitely be more of an incentive to buy. As it is now it is awesome, but the function would ultimately sell it for me. As portus mentioned I use the free one too, and that works nicely for what it does.
