I've gotten requests for a "quick-start" guide, which I plan to add. I also plan to add a FAQ and/or a "how-to" guide for common questions and tasks.
My baseline for any release is 100% complete reference documentation, meaning every method and all its options are documented. For people who learn best from reference-style documentation, this is extremely helpful. Worst case, someone can post to the mailing list and I can point out which part of the documentation to read.
But with a very big, feature-rich module, it's hard for some people to find a "way in," so to speak. The existing tutorial was my first step towards helping with that, providing a narrative-style exploration of the major features as well as examples of best practices. I think the quick-start guide will be next.
If anyone has any more suggestions, just email me or post to the mailing list
