Perhaps Steam will soon update the interface of the download tab

SteamDB creator and general data-sniffer Pavel Djundik has managed to access the new-look download page.

The new look is visually consistent with other recently overhauled elements of Steam, such as the games library. The information displayed is more-or-less as it was, just presented in a more eye-pleasing fashion. It's worth adding the caveat that this look could change when it's officially released, but the style lines up with what Valve's been doing generally.

Djundik went on to say that "They're working on a new settings page as well, but it doesn't open so easily though. Looks like Valve is slowly but surely heading towards removing VGUI.
