Andrew Ozz came through and sent over the latest revision of the new API for TinyMCE which will find it’s way into WP core hopefully in WP 3.3 — It’s not implemented in the brand new PodsFormUI class just committed.
@wesbos and @jchristopher are collaborating on the new fields, but so far I’ve got a few basic ones in there. The idea is you can extend PodsFormUI to add your own set of fields if you’d like, overwrite existing ones, or just hook into filters / actions to do it the boring old procedural way. Of course, there’s also always input helpers 🙂
So I’m working next on finishing up the new PodsForm / PodsFormUI / PodsData classes for integration with PodsUI so we’ll have a working backend again for the 2.0 branch!
