I would be OK with Request_Delete and other similar procs/functions not being in the list if they were included in another list that would help to automatically generate the stub code, the same way as clicking on an Event in the Properties dialog does. Maybe a "Methods" tab, right after "Events'?

For reference, the Microsoft .Net Code Editor has a combo form at the top of the IDE that gives you a list of all available methods, properties and events for an object. It differentiates them by icons. I'm not saying that's how DataFlex should do it, but it does make it convenient to be easily able to select what handler you want inserted from a list...
