Isometric Perspective View

Being able to export the image with a slight isometric angled view will increase the readability of the map (especially for big maps and doors in general) and you'll get an iconic feeling as a bonus.

The angle stays the same across the map (like an angled orthographic view).

The best would be with an option for the angle so people can freely choose the side and if it's a true isometric or a slight angle.
