i thought it would be convenient if we accidentally hit the wrong vote button or if you change your thoughts about a creation you could simply click the other vote button. but instead when you click it, it will just be totally locked in and you cant change it. :(
EDIT: this should have been called "revote option"
NO, you shouldn't vote on things so quickly. I vote up only for obviously good creations, or down for creations asking for votes. and i've never ended up wanting to change a vote.
@cracker64 Some people like me always have a 1920 X 1080 resolution making the PT window smaller, it is easy for me to accidentally press the downvote button instead of the upvote button.
