If I need to build a timeline in Shorthand, this is currently only possible with hacks: using Reveal Sections with a (time)line-pattern as background-image or using a Scrollpoints Section. But especially if a story needs to be build fast (our example was the death of the queen), this is not very suitable.
Cool would be to have a decent Timeline Section where you can set a timespan and simply add some points on the line (like adding scrollpoints) and style the line, the dots, the background ...
Moving through the timeline could work either via scrolling or arrows.
A source of inspiration could be the timeline feature of Flourish:
