Could you post all the settings used for the first image? I can't for the life of me figure out how to make it look like that... but then again, I may be blind or an idiot xD

Enable "Use game background image as window background" in Settings->Appearance->General. Blur is disabled in my screenshots.
Disable "Background Image" in Settings->Appearance->Details View.
Enable the Sidebar in MainMenu->View->Sidebar->Enabled.
