vertical axis, profile details, comparative timelines, documents

hi. i love your product. i would suggest a few improvements.
1. it would be great to be able to choose the height of events on the vertical axis. 2. it would be really good to have a larger profile of the timeline/user. 3 to be able to have parallel timelines to compare concurrent events in 2 places would be very useful. 4. being able to view documents as events would be extremely useful as it would turn a timeline into a blog.
