An exi decoder/encoder (goal is to have modes for spec conform and interop, which right now doesn't seem to be the same thing). Afterwards I also want to try to use it to encode huge XML datasets in precomp mode with good encoder (maybe ztsd). Should be pretty useful for large repetitive datasets. I also want to build a tool to visualize XML to exi de/encoding in the browser.

Ah yeah, and also a suite of web games/apps in rust wasm all based around collaborative creativity. The one for collaborative storytelling is most mature, currently playtesting with friends.
