About #1: I wasn't intending to offend or snap... I just meant that it seems like an obvious option that people would like to have.
#3: I meant like you can make a selection-outline with the magic wand, BUT this would be afforded to the clone-stamp tool, in which you could outline any shape you wanted to clone, and then paste it exactly as shaped.
EX: Say I wanted to fill a blank triangle with a pattern that I intend to clone; but since the shape of the clone tool is a circle, it means that some of the patterning isn't going to match up. I was thinking that there could be some kind of clone-Lasso that you could outline any shape and then paste that exact pattern. So if I need to fill up a triangle, I lasso a triangular shape to better match Vs the default circle... I hope that makes better sense?
Also when trying to fill shapes and areas that aren't circular, a very (to me) noticeable, overlapping pattern presents itself. This makes blending multiple, non-circular areas, much more complicated since the patterns will not blend as easily as if you were using a similar shape, which would make blending ascend/descending (horizontal and vertical) much easier since the circular-clone-pattern doesn't match the linear lines of said rectangular shapes etc.
I hope this makes better sense? And again I think is this one of the best programs for picture editing and manipulation... oh and it's FREE! AMAZING! *Thumbs UP*
