In short, I would like to see FormZ concentrating on its core modelling ability and on those items that need to be done in 3D eg. BIM, schedules of materials etc. (Profiles in the Lab are a great start to this!); keeping tools like Layout and Renderzone but understanding that they will only ever satisfy a small percentage of users and making a great effort to ease integration with other programs. For me the first step would be to implement Openclip copy and paste out of FormZ.
This seems a sensible compromise (certainly in agreement on the Layout side of things). This strategy would need to be backed up by clear documentation that clarifies that Layout isn't attempting to compete with specialist 2d programs but providing a set of simple tools for those that don't already own a specialist 2d/layout package. And I'd also agree that it's the IO plugins between programs that needs the most attention.
