I haven't played luckyb.it in a while as well but saw people talking about the new layout so was curious
Design wise it is nice to see the blockchain hashes as a clickable option but the old symbol did look nicer.
Just my 2 cents
Old icon symbol was also clickable. It just seems a bit too poppy (in a bad way) for the mellow dark background. The bright light blue on the dark brown and green background just looks bad.
