Currently in the detailed Issue view there is a Vote link sporting a Thumb Up icon to vote for an Issue. But this leaves (Agile) Thumb Sideways and Thumb Down voters sharing the "non vote".
This should be fixed so that Thumb Sideways people don't vote but Thumb Down voters have a say in the outcome by being able to "Vote Against" an Issue.
Or perhaps a radio button instead:
o Thumb Up
o Thumb Sideways (default)
o Thumb Down
Anybody else think this makes sense?
