Selector-Connector promotes reusable layout objects in a way that's become more important with FIleMaker 13. You may have seen Todd Geist and Jason Young speak about this at PauseOnError in Portland. This is also the pattern we're using in the new SeedCode Complete template.
Jason's just put together a nice article about the problems we were trying to solve with this approach and how that led to "bending the rules" of Anchor-Buoy and the Selector-Connector pattern for the relationship graph.
Anybody else using something like this?
