Hello,
it would be very useful if it was possible to modify the selection rectangle when using the marquee tool. Ideally, it should behave the same way the crop tool does, i.e. one can drag sides and corners of the current selection to modify it, with modifier keys for various constraints (square, proportional etc.) also, being able to force constraints on a selection is great.
Currently, for me the only useful way to create rectangular selections is to create a rectangular shape and once I am happy with it use layer to selection (which is not a bad workflow, but I'd love to not have to use this).
Many thanks for great software!
Cheers
