Event timeline display di Andy Gray

Events from Wikipedia can be added by right clicking on the Wikipedia page and selecting "Save entry to timeline". This will display a window that (usually) contains a summary of the information from the Wikipedia page with the option to save the event as a member of a category that you define. Edit this to your liking or accept it as it is and click "OK" to save the event. To see the timeline of events that you have saved, click on the Wikipedia icon in the Firefox toolbar. The new tab that is displayed contains the timeline you have saved, with a menu to add new events / timelines /etc. When the cursor is on an event in the timeline, the summary from Wikipedia is displayed. To edit the event, click on it on the timeline or the summary display. All events will be saved for as long as they are not deleted and the extension is installed.
