When trying to produce a map with trees in Ortho mode, the trees' canopy blocks all other objects. 

Having a toggle to convert them into either leafless trees, or stumps, or something like it, would be great to produce two different views of an area with one of the views unobscured by all the foliage but still presenting that there are trees where they are.

Edit: Or even have the leaves be at 50% Opacity or something. That'd work too.
