User Real Engagement

More than 7 years ago there was a statistics service in Russia ( they were bought out by a big company and it had changed a lot )
Mainly they provided a heat maps and ability to record everything that user did on site.
But I didn't use a lot of user record playback, however there was one of the greatest features that I can't find anywhere else anymore.

Add the ability to see the user REAL engagement on each page by providing a timeline (for example as a progress bar), that is colored with different colors which will represent:
1. When user was moving his mouse/scroling/typing (green)
2. When his browser window was inactive (did something else in other tab of his browser) - gray
4. Opened any element of the page, Javascript and so on.

For me this was a great tool to see how active each user and his session was.

I think this would me a great premium feature!

Not so cool, but it helped a lot to find user that engaged with site a lot.

User Activity
I can't remember was exactly it showed, but main idea is that is measured the overall activity(engagement) of the user during his session.
It was a sum of page viewed, time on page/ user action and other.
