Chronicle of History

Sorry if someone suggested this already but it would be easy to convert this app to a chronicle of general history- i.e. have a means adding significant nation or world historical events - there are some apps that go some way towards doing that, but what I'd like is a means of adding the events myself relating to what I'm interested in - momento can almost do this as is - but it would be good to be able to rapidly jump to a particular year in world history - either with an update or an entirely different app with similar functionality.
