1. Merge Layout and Modeler into one app.
2. Problem solved.!!

(ahem....) In all serious, I'm not a "set extender" kind of user, so my opinion won't count for much, but it still seems sort of counter productive to keep going back and forth, as was stated earlier. So, to re-iterate, you've either got to have more modeling tools in Layout, or some way to have Layout's camera features in Modeler. Either way, isn't that one more step towards a unified app? <ducks to avoid things thrown>
