When the crop tool is in use, the mouse pointer transforms into cross-hairs with a crop symbol. The cross-hairs are dark (black&?) and small, while the crop symbol is large and bright. The image areas outside of the active cropping area are very dark, making the black cross-hairs unnoticeable.
I would like the cross-hairs to be obvious and usable on either dark or bright images. The crop tool symbol next to the cross-hairs could be less noticeable.
(I only found the cross-hairs after weeks of use.)
