Does it work in Firefox? Not here...

Suggestion 1: you could show the name of bigger entities also in the corners of the screen - now you must scroll up to Italy to see that the green region is the Roman empire.

Suggestion 2: I expected to be able to drag the timeline left and right. Dragging the cursor over the screen edge for the next time period makes you unwillingly jump a few hundred years.

Working fine for me on FF. Once or twice the timeline stops working, but clicking around a bit brings it back.

Works in larger resolution for me fine, issues on smaller viewports.

Works fine in FF on Fedora.
