The Skype for Business (CTR version, via O365 SFB Online) user interface is about to get some minor changes soon (depending on your deployment (current/deferred) on O365). How it  might look like you can see on the NextHop Blog >>here<<. It might be subject to change. I guess that these updates will follow afterwards for on premise users/client versions by the default update paths (Microsoft Update) which is not yet mentioned on the blog post.
