I suggest we swap the order of Thumbs down/Thumbs up buttons in the "Rate this result" tab.
I almost hit Thumbs down for an image I liked because I'm used to the regular order I find on Facebook or LinkedIn, YouTube, where the first button (the one on the left) is the Like button (so Thumbs up), and the second button (the one on the right) represents a second option. In Firefly they are swapped and create a bit of confusion for the first few seconds. It's counterintuitive. It would greatly improve user experience if the buttons would follow the regular order: Like (left), Dislike (right).
