Expanding "Activities" to Full Screen in a Case

Hi All,

         I am a n00b and have been tasked with rolling out and configuring Dynamics 2016 (cloud) in a production environment. I have started with the service side (contrary to typical rollout).

          We are in limited production deployment right now and I have been soliciting feedback from the support team.

          The most popular request I have been getting is to find an easy way for support Engineers to quickly expand the 'Activities' of a case to full screen and to have each 'Activity' (Note, e-mail, phone call, etc) expand. 

           Any ideas on how to make this happen?

Thank You,
