I am proud to present a massively improved timeline search and visual timeline: I have categorized every timeline entry (which took quite a while, considering we have over 1000 entries, even though I did get some help) and you can now search the timeline by category. Categories include "Philosophy & Religion", "States & Territories", "War(fare) & Battles", among others. I've also greatly improved the visual timeline feature: Each timeline entry is coloured according to its category, and the positioning of entries on the timeline is now working much better. I'm hope you're going to love this feature! As always, feedback is most welcome!
