Overview and features

Hi
I need to understand if WPMU is what I need.
I am a web designer and I do a lot of small business wordpress sites. All of them individually hosted. I am looking for something that will decrease development time. I am currently working a lot with Divi from Elegant Themes. What appealed to me about WPMU was that it seemed to be a more visual editing interface. I've never used the multi site option and I doubt that I do have a need for it. What I would like is the functionality of MainWP but with WPMUs themes and graphic editing. How can WPMU help me? :slight_smile:
