Hey Brim,
I'm glad that you find the timeline so useful. Comments are great.
The Spacemaster timeline is a good idea. One of the things on my to-do list is to add the ability to filter viewing of entries by source. In other words, a user could deselect Spacemaster entries and would never see them. Likewise I could put in entries from non-canon books, or even from individual's campaigns, but every user would be able to filter out those entries if they wished. So I'd like to do that before adding any entries from SM - however I'm also quite busy now, so it's low on the list. The fields for Source are already in there and some entries have already had source info added (such as Demons of the Burning Night), however not page number and I can't imagine I'd ever have the time to go look up page numbers, plus many entries appear in many books.
I may be able to export the timeline from the database and get it into Excel somehow, I'll give it a try.
