Sometimes it’s useful to see the 3d world you are creating from multiple different angles simultaneously. Many 3D programs like 3Ds Max even offer quad views that have four different angles available. In Unity you can view your scene from multiple angles in the editor by right-clicking on the scene window tab at the top and choosing “add tab” and then “scene”. You can now drag and drop this new scene window tab to a place in the interface that you prefer and change it’s view angle to your liking. One way of working could for example be to have always one top view available and next to that one free view.
