Allow "Hide Top Toolbar" to be enabled separately

[mr-cheffy]

What feature would you like to see?

Would love to be able to hide the top toolbar without having full compact mode enabled. I like being able to see my tabs, but want to hide the address bar.

What platform are you seeing the problem on?

Linux
