On touch UI features status, MSM/Blueprint Control Center stated as completed but I couldn't find it anywhere. All I am seeing is Blueprint configuration which is not the same as Blueprint Control Center to control rollout configurations.
You can use the sample URL below to open the Livecopy overview in touch UI:
http://<host>:<port>/libs/wcm/msm/gui/content/livecopies.html/<PATH OF THE BLUEPRINT>
