So, this always bugs me when I'm submitting a post, and I don't know if it has been submitted before, but can we have a menu of suggest tags drop down when we start entering one?

Kind of like on Google if I type in "sug-" it auto-suggests "sugarfish" "sugar cookie recipe" etc.

If it would do that using existing tags in the tag box it'd be great and help people submit to existing tags instead making random new ones no one will find.

See, making this, I wasn't sure if I should enter "suggestion" or "suggestions" as a tag. One is more popular than the other. If they were perhaps ranked by popularity, or came with a # of posts next to the name, it would make tags more efficient I think.
