Originally based off Windows Longhorn, Plexed's turned into a much bigger project than originally intended.
You can find the Steam group here. Segoe UI and Segoe UI semilight are required. Segoe UI is included in any modern (Vista or above) Windows version, and Segoe UI semilight is included in Windows 8 and above. The download also includes Segoe UI semilight for users on Windows 7 or Vista.
Plexed Finch brings back the bottom bar for the sake of easier access to downloads for some people - it's otherwise identical to the main skin.
Could you possibly add a customisation file that allows us to change the colours/images/fonts of the skin, like what Metro and Air do? I'm personally not a fan of the ribbons in the topbar, nor the current colour of the skin.
