This is always a tricky thing to get right.
(but if anyone can build options and enhancements than Gil and Dan can !)
Hate to refer to LSP , but by the time freshers (including myself last year) , found out how the rendering across the stage v/s model worked and important it was to ensure that the location and how you drew your models was "correct" , you were basically sc***ed for that year when you finally got good enough to try some macros etc. No one then has the time or inclination to redraw everything and face all the disruption.
So you end of then using the effects that are agnostic to this layout.
