Aeon for reading history books

I have trouble reading historical books because all of the dates.
I have a difficult time visualizing all the events in relation to each other.
(When the dates jump back forth in a non-linear fashion.)

I hope to use Aeon Timeline for reading history books and writing down the thoughts and events to keep track of events.
I know Aeon Timeline is used for people writing novels.
But I thought using Aeon Timeline in reverse to track and visualize events, would be a good use.

My suggestion is maybe you could increase the icons available to include this approach. An icon for philosophy or published is what I was looking for, to represent their outlook on life or what they believe in or the date for published title.

I am open to using Aeon (version 3) in it’s current form.

Any suggestions?
