Idea referenced in the link below.

This idea is already implemented in the preferences menu under Units & Increments but it's only applied to keyboard shortcuts. I don't see why this setting wouldn't be included for the tracking and kerning settings in the control panel. As mentioned in the link, needing to let go of the mouse just to adjust tracking is a nuisance.

I never increase tracking by 10 when typesetting to adjust for the rag of a text block. Having the increments hard set to 10 effectively makes the control panel useless to me when typesetting. Oddly this isn't an issue in Illustrator, where values increase by one, the program where I ironically would be more likely to use more artistic license with text spacing.

Searched for the idea but I saw nothing here.
