Point of MultiSite

Hello,

First of all, dealing with a Rookie here.

I am contemplating setting up MultiSite. I will explain you guys my scenario to see if MultiSite will be fitting or useful.

I own several different domains (kangarew.com, luvmemo.com, itsuu.com, costaricaroofing.com, etc., etc.) You get the point. However, each site has its own separate theme, its own different plugins it uses, and its different purposes. I wouldn't think of it as a "network".

That being said, I WOULD LOVE to automate my website processes more, and expedite the effectiveness of editing/maintaining these sites if I could do all of this with one simple control panel login.

Is this what MultiSite can do? Or do I have it all twisted?

Thank you in advance for your feedback.
