Crappy app. Very fickle, does not play with drag and drop from the Mac Color Picker or other apps (actually it does one time out of ten.. so I guess it's meant to ? But just does not work). Basically it's an "autistic app. I'm on a Mac.. I want my apps to integrate, not to play on their own.
It can import color sets fine like CLR files, but I want a simpler drag&drop approach to work well.
Plus the interface is not that great, it looks a bit "toyish" really.
PS: Tangerine was sooooooo good, but unfortunately the dev let it die, same with ColorSchemer. The only two apps IMO that got things right.
PS: This "color apps" area is really lacking.. Which is odd considering the Mac is the platform of choice for people working with color amongst other things..I wish some dev would make something that has possibly an interface the like of ColorSchemer and a menu access that can float on top of other apps when need be.
