A few observations on the medal system since the redesign:
Medals seem to open automatically on the games page when you unlock them in the game. No more refreshing the page to see if they sent or not - at least with the ones connected to the API system .
Secret medals stay secret. you can only view them in your own profile when you unlock them, but they seem to be locked when you go to other user's pages. That sucks. It's going to make it harder to find out what they are.
I hope it's a design flaw, but clicking on medals send you to the user's medal page, not the game. This sucks, because now that they don't have the game's name on them anymore, I have to dig around for the game they came from, instead of clicking on them and going directly to the game..
