Thunar has the ability to add custom actions and other file browsers like PCManFM have the ability to open a folder as root. Where is this functionality in Nautilus? I see there use to be an extension called nautilus-gksu but the package is not in the repositories anymore. I've tried a few different guides on how to get this functionality in Nautilus but I have yet to find anything that works. I also tried the custom action extension for Nautilus but it does not appear to do anything.
