At long last we have a proper top, left, and front orthographic editor view! This should make aligning objects much, much easier.
There are a few bugs to work out - the scale tool in particular is hard to use in the top view. You'll also find that when you create an object from the side or front, it's X or Y location is probably not what you'd expect. Other than that, this should work pretty well.
Note that the focus button will not return you to perspective mode - you'll need to switch to orbit then hit the focus button.
You can get to the top, left, or front views by clicking the little plane icons in the toolbar ( Under 'rendering' in this screenshot).
Now that this is all worked out, stay tuned for an Orthographic Camera Entity that you can use in your sim!
