Reflecting over the request to be able to copy and paste controls, I imagined how easy it would be to be able to modify configurations from a desktop / laptop computer and load the config on an iOS device from dropbox. It occurred to me that, at that point, full functionality might as well be available.
This is a large request, but I think HomeWave is the most appropriate App out there for this and I would pay additional for the program.
The idea of a consistent, familiar control interface on all your devices and being able to edit, save, and load configurations across platforms would appeal to users more than just myself.
