I asked for this before, I think, not positive, but Quasi-3D cards that always face the camera is something I really need, and probably other people for various pseudo-3D elements.
For example image-based vegetation could be used in TG, as well as many other stuff. Birds, or animals at a distance, or effects like fireflies, particles, etc. So that way they area all correctly oriented at the camera and appear to be in the 3D world.
Currently, you'd have to add all the cards manually and orientate them at the camera, but a setting to have the card always exactly facing the camera would be amazing. Especially for a population.
Bonus if a card could also be a cross-based card. 2 cards at a center axis for 4 parts for cards not facing the camera, but could have some cheap fake effects, like PNG\TIF grass clumps.
