We know a lot of you are having to write custom renderers for your apps. This was fully expected, and we are of course working to minimize the number of renderers you need to write (it will never reach zero for large enough apps) and making writing them easier. We have a good idea how to make it easier but what we really need feeback on is what you are writing them for!
So if you can just help us and give us some feedback on what custom renderers you wrote and what features/modifications you made with them. It would really help us understand the biggest holes in the API and were to start plugging!
