The Account Icon Browser is relatively unpractical. The Icons are too small and the available space is not well used. I did a quick redesign of it: Click!
You can browse trough the icons and thanks to the bigger size they are well visible. As addition, if you hover over an icon it will increase in size and provide you with a "Buy" button and the price of the icon. As seen here.
This isn't a definitive design, just a draft. What do you think about it?
