Hi, First, thanks for the efforts on this great piece of software. Love the interface, bravo. My question now : maybe I'm missing something, but is there any way to have a fixed size or a proportional size for the rectangle selection tool ? (i.e. 1x1 for squared selections or precise pixel sides sizes or so ) Can't find that function in the help but I may have missed it. Thanks anyway for the great work, keep up ! Pierre
