How can I turn off window titlebars (window decorations) in gnome shell/mutter?

There's a shell extension called Maximus that disables window decorations when windows are maximized, but I'd like to disable window decorations entirely, for all windows (just using keyboard shortcuts to work with them). Is there an easy way to do that?


I figured out how to do it myself, following the instructions under "Method 2" here, but making those changes for the block beginning frame_geometry name="normal" instead of max. Now I don't have any borders. Great for using the extension Shellshape as a tiling window manager.
