I'm almost done with new stuff. The whole reason to introduce the mechanic was to strengthen the Storytelling tech, and with this addition, every tech is now fully supported with 2 full tricks' worth of content. The techs that couldn't meet the 2-trick threshold got cut. In fact, most of what I've been doing over the last few months has been either getting every single tech up to the threshold or just organizing existing stuff so that it flows together.
There are now definitely places where we don't need anything new; I'd have a hard time with adding any new units or religions. New buildings would almost certainly need to intersect with existing buildings to be worthwhile; I'm planning to do a hunt for "orphan" buildings and see what we can do with some of those. I'm not in favor of new civic categories, but I think there's still some room for civic choices. Anything beyond XML-adjustments are way past my skill level.
