Hide the origin and "square floor" in blender?

I’m trying to display some things in blender and want to hide other things to improve focus on what I’m pointing at.

For this purpose I want to hide the origin and the “square 2d” plane that is shown in Blender.

Can these be hidden by some simple measure?

Turn off the manipulator

Turn off the grid or select ‘Only Render’ (shortcut N to toggle on/off properties panel)


Thank you sir, works like a charm!
