Spinners are insanely small. Make them larger.
Operating System: Win7-32 GIMP 2.10.20
Description of the feature
The spinners on the controls that have them are extremely small compared to the mouse pointer. See screen shot below where the mouse pointer is on the Size's lower spinner.
Use cases
When I need the precision that is not possible to get with the slider, getting the mouse pointer at the right spot is difficult--the target is too small.
Make the spinners larger. One way to do this is to increase the size the controls that accompany the spinner. For example, Opacity, Size, Aspect Ratio, etc. should be as large as the font in the menu bar.
