Feature: Need more perspectives (Orthogonal left, right, top, bottom)

Hello,
I'm currently trying out BabylonJS because I'm dissatisfied with NeedleEngine in Unity. I have a lot of experience with Unity, Blender and many other 3D editors and CAD programmes.

And what I miss after just a few minutes in BJS.Editor are clearly the quickly accessible perspectives. So top, left, right, bottom in orthogonal display. To quickly align objects and so on. In my workflow, I constantly switch between views very quickly. Therefore, I would really like to see this feature.

I tried to solve the problem with separate cameras set to ortho, but that's also awkward because their position and viewing angle are not easy to change. They should be as easy to use as the editor preview camera.

Thank you very much for this great project, I will continue to follow it.
