While I applaud finally adding the vote up (and even vote down) features, this feature look a bit overdesigned. I don't really get how I should "love" an issue, or "this issue makes me happy". Or the relevance of a "thinking face". The ui would be simpler with only 1 or 2 icons. At least there's no "this issue makes me sad/angry" buttons.
