Currently the editor displays the leftmost pixel (X) and the topmost pixel (Y), plus the width and height of an object.
Sometimes I want to arrange things from the right or bottom, and that’s a chore right now. You can get the rightmost pixel (X2) and bottom pixel (Y2) by doing a little math, but it’s tedious, especially when you have to do it over and over. Being able to view and edit those values directly would be incredibly helpful. The editor already knows the values (it’s just X+Wide and Y+Tall).
