Adding this suggestion here...so other folks can vote for it.

(Speaking of voting... it would be great to see the list of WHO voted, and also the feature that people could vote AGAINST a feature – so if 200 people think my idea is great... but 200 others haven't voted because the think it's crap... Atlassian would know the score. At this point, it's biased to the vocal majority.)
