Suggestion for improvements to the selection cursors
Operating System: Xubuntu 22.04.1
Description of the feature
I'm using GIMP 2.10.32 on a 4K 3840x2160 with standard 1.0 scaling. Certain cursors that appear as crosses are very small and the "notation" sub-icons that appear are almost invisible. For example, when performing a freehand selection, the lasso is fairly clear but the + or - associated with the cursor is extremely small and difficult to see. If it would be possible to provide some fine-tuned scaling feature to these icons, it would be helpful. Not all icons need to be scaled up. The windowing pointer, for example, is plenty big. (I can't get a screenshot that shows the cursor, unfortunately.)
The second improvement I would like to suggest has to do specifically with the + and - notation. Given an initial selection, then you can add (+) to the selection or subtract (-) from it, typically by holding down the CTRL key. When I start a free subtraction selection holding CTRL, the minus sign is displayed. After you start the subtraction selection you can release the CTRL key and continue. The problem is that the plus sign is then displayed which seems to be telling you that you are in an addition, not a subtraction. I'd like to suggest that the minus sign continued to be displayed until the termination of of the selection operation as reassurance that you are still subtracting, regardless of whether the CTRL key continues to be held.
This may seem like a foolish nitpick, but one of the most aggravating things I have done repeatedly is spend a lot of time creating a complex subtraction selection, only to find out at the end that it was an addition selection! Since there is currently no way (that I know of) to invert the last selection, this means I have to undo and recreate the selection from start. If the cursor continued to show the minus, then if I saw a plus, I could abort early in the process. Note that the "Subtract" Icon on the Free Select tool menu also reverts to Addition when the CTRL key is released.
I hope all of this is clear.
