Guys, you really NEED TO USE the steam browser to open the panels you have inside the game.
Though steam is much more than that, can click in the panels and opening the browser into the overlay system from steam is incredible needed/suggested and it is obvious that we need to have this function.
I have to add that I am really impressed that at this 1.0 launch this was not implemented yet, and pray that this will be coming one day
PS.: I believe I posted this in the correct forum category.
