1. I would really love to see the timeline be more interactive. It's a little cumbersome to use. It'd be nice if you could narrow the search or topics and only have those items displayed. It looks a little outdated as well.
2. I would like to see more dates, or the ability to purchase to add more dates to the timeline (modern, world history, etc).
3. I added the map in here because the current way of clicking or combining custom maps is a bit cumbersome as well. The different categories make it a bit difficult. It would be nice to have the option to have interactive timelines and maps.
