Alright folks it's time to talk about the elephant in the room

Steam has released a new design for the Friends list which may have affected how SteamCustomizer skins looked if you downloaded them prior to the update.

Here's what you can do:

Redownload and re-apply your skins from the website

This should fix issues with the layout as the skinning engine will "build" the skin based on new Steam files. You can even locate your *.stskin files and just open them again.

You can also disable the custom skin from View > Settings > Interface - selecting < default skin > or from Skin Manager (in your startmenu)

Meanwhile, as far as supporting the friends list skinning, we're not sure yet as Valve still seems to be developing it and it's not finished.

Skininng the friends list is not possible at the moment

We hope that eventually it will be possible to skin the Friends list, in the meantime that's not possible. Additionaly, we will be closely observing Valve's developement of the theorized new client UI and try to modify SteamCustomizer to support it.

That's all folks!
