Ben, Question for you. I've been looking at the UM extensions as well. How about your support for chaining? From what I've seen it's chaining commands, not events.
My main needs are to chain events, and right now I'm using a very wordy (ie, many class files) to do that. Separate classes for a chained version of each event. A description/implementation example on the download page, or some reference would be really useful here. thanks, jon
