Consider put less attention to issue/mr/todo count on header in case of 0
The colorful approach to header counts does not work for me since it takes constant attention no matter if there is 0 issues/mr/todos or many.
As proposed solution I would expect counter to be gray (not noticeable) color when there is 0 items in it. Example
Design
when counters are 0
show no count badge
