The ability to disabling the color class label with the same key (Key "1" turns on and off colour label).
Please add an option in settings, that provide
possibility to mark and unmark colour labels by the same button. For example: Key "1" gives red label and then the same Key "1" can clear it, and leaves the field blank. This affects effectiveness, because
decision can by done just by one finger that waits all the time above one button. And if decision is bad, or next photo is better, this decision can be changed on previous photo by the same Key, without looking for Key "0".
This would greatly facilitate quick selection for some workflows.
I know there is Tag (T) checkmark, that has this capability, but it is poorly visible (till now), and not comfortable to use in practice.
Simple things make huge differences

thanks
