I know that I mentioned this in a post in the scheduler forum but now that there is a forum for new features this one should definitely go to the top of the list. There appears to be connectors for a few other tree type components but not the TreeTimeline. I was told it was in the works. Right now the only known data support is JSON. There is not even XML support for the TreeTimeline. There is three main data sets when talking about a TreeTimeline which need to be considered (The tree/y_unit data, the events, and the marked timespans).
