Menu bar auto-hide

This is either a question or a feature request. When in full screen on Omnioutliner for the mac, the top menu bar autohides by default. I’d like to keep it fixed since I refer to it frequently, but I have not found a way to do that. Apologies if I overlooked something simple.

Sorry. Hiding the menu bar in a fullscreen app is a system-defined behavior.

By system-defined you mean the OS? because other apps, e.g. Omnifocus, do not have that behavior.

Oh, I see the confusion. I did not mean the system’s menubar, I meant Omnioutliner top toolbar, which is also hidden by default.
