List of features supported by the Lync SDK in UISuppressionMode

Question

I'm currently developing a custom Lync client. I need full control over the UI. If possible could anyone provide a list of all the supported features of Lync client's SuppressionMode API?

i.e. Desktop sharing? File Transfer? Docking of the VideoChannel? Instance messaging? etc..

-- Edit: New info

As it says here in the link below:

With these lower-level API’s we can implement our own client but it has now become a much larger task. Things that were for free, are now very big implementations we must develop ourselves rather than customize:

Does this mean that there is a way to use\access these advanced API features, and what's left is the development of the custom user controls?!
