I don't think anything new in Quesa is needed for that -- I do this 
all the time, and it's easy enough to simply rotate those objects to 
face the camera whenever the camera moves.  Note that some things you 
want to have exactly face the camera (e.g. for sprites), while others 
you want to only rotate around one axis, as in your tree example. 
But both are easy to do yourself.

Best,
