In Healing and Cloning "cursor"-arrows etc. sometimes obscure important parts of the image

What problem do you see this solving?

Example: I have a horizontal feature (an edge), and I want to clone from a distinct point along that feature. Then the line from the cloning source and the target area typically is placed just on top of my horizontal feature. In particular it is very difficult to place the cloned area in such a way that it exactly and invisibly hits the horizontal feature (the edge) - it's far too easy to misplace the copy just so that it's a pixel or two away from the correct position. Same if after a mishap like that I try to fix it by gripping the cloning source circle and moving it. It would help, if during cloning I could press some key that would temporarily not show the cursor graphics.

When was the last time you were affected by this lack of functionality, or specific tool?

Nearly every time I use cloning or healing
