Hello !
I'm new here, and post cause of my frustration by using the crop tool. So here is a Christmas wish-list for this tool :
the "esc" key on the MacBook Pro is really able to escape the crop tool
the Maj key apply a size constraint
the Alt key apply a symmetric constraint
the crop tool is able to stick to the pixel grid
and at last, the ability to choose a destructive mode, even if there is the trick of Layer > Rasterize & Trim (cf. below).
And an other demand, out of crop tool but associated to size management : when creating a new document, having the ability to make it the same size of the image in the clipboard, to avoid to crop just after pasting…
Thank you Affinity's Santa !
