I am aware that we can click view and then hide all of the sketches. planes, etc. But then when creating a new sketch or plane, we need to undo that and BLAM! Our assemblies are an incoherent mess again.
What a game changer it would be to simply right click on a part or assembly in the browser and select "Hide Stuff".
That way, we can keep creating new parts and not worry about having to hide all and then show all again.
