I've read the articles from Brian Pepin about Cider Extensibility but can't find anything of that stuff in the feb. CTP. Knows anyone about design time features in that CTP?
We use Cider's extensibility points (Extension, ExtensionServer, EditingContext) internally to implement Cider and thus the architecture that Brian discusses in his articles here and here is in the Feb CTP.
At this point, we don't have an SDK but you can search for the PresentationDesignCore.dll assembly, reference it and write your own Extensions and ExtensionServers.
Unfortunately, again due to the fact that we don't have an SDK quite yet, there isn't any documentation to help you. I do have a sample of writing a CustomInstanceFactory on my blog here and plan to post an example of writing an adorner. Stay tuned.
