At some point (OF1?), I knew how to create a perspective that hid the sidebar and toolbar. Is it possible to create a perspective that hides the sidebar and toolbar.
If this isn’t possible, I suppose I can make a keyboard maestro script to invoke the perspective and hide the sidebar/toolbar.
The ability to show/hide various toolbars/sidebars as part of the settings of the Perspective view has been a feature request since the V1 -> V2 update.
