Today's Gratitude Item: That I finally fixed a minor issue with the layout one of the websites that I maintain. Realising that the rounded corners were overly complicated and not worth the effort was the key. Said site now features "normal" corners which look great and don't break like the rounded corners used to. Note to self: In future, keep things simple!
