Mini Map in scroll bar?

[Jelloeater]

Is your feature request related to a problem? Please describe.
Not related to any problem, just a new feature.

Describe the solution you'd like
Search highlighting in scroll bar, it's a feature in iTerm2 (and other web browsers), that I think would help alot for going through long scroll backs.

Describe alternatives you've considered
No alternative that I'm aware of, aside from the iTerm2 implementation, which I think is nice.
