Any idea how I can get rid of that title bar that sits on top of the tab bar? In the demo I saw it's not present or it may have been cut from it.
Linux
That said, if you use GNOME Shell, the Pixel Saver extension is great for me: https://extensions.gnome.org/extension/723/pixel-saver/
Was using ~cryptic setting in Hide Caption Title Bar Plus to accomplish this, but it not ported yet.
I'll give it to them though it does seem fast.
In the lower right, there should be a toggle for it.
edit: not sure if that's linux friendly
