marquee, lasso, copy & paste and etctera...
AR2 is too good for me to give up of it! By the day I leave Photoshop to use exclusively AR I will open a champanhe! I am sure there are lots of cartunist who does comics like me, that will migrate to AR quickly, the moment these features (copy & paste and so) come to be released.
What I see today (at least back to Brazil) is people doing the first stages at paper (pencil, pen and rubber), scanning it, and going to corel or psp to the other steps.
Because I go straight to the tablet, I spend half the time...
Market considerations are important, and multiplying the Users of AR will be good for all of us.
To the purists, I can say only - Don't use it!
