Nice

Please add some basic photoshop hot keys like hold spacebar (for free positioning) and shift key (to specify the correct proportions and right angle of lines) while draging shapes.
It would also helpful to be able to edit the size and positioning of elements already drawn. Some of these features are already in Mac Preview (annotate feature).
Thanks for your app!
