I'm struggling with the Page Layout s in Lightning and how much space they take up. i had one thought and that was to create one tab say 4 of my related lists. Then I wanted to create another Tab and add related lists for activities. I don't like the Activity component because it does not appear I can customize this. 

The problem is when I try to add Activity History as a single related list on a tab it won't let me because it is not in related lists for Tasks. But the whole point  is i DON't want to see all t his clutter in one tab. People are having to do far too much scrolling up and down. Is there a way to accomplish this?
