A timeline (as shown above) contains one or more bands, which can be panned infinitely by dragging with the mouse pointer. A band can be configured to synchronize with another band such that panning one band also scrolls the other. The band also takes an event source which provides events to be displayed in that band. Different bands can have different event sources.
This is a work in progress that may take years to fill. I am aware that many events are missing. I’m working on it. — Editor
