The upcoming version of whynotstr (0.0.0-prealpha1) will have some cool things:

* a new (maybe nicer?) editor
* MULTIFUCKINGCURSORS! (you can see your invited (and maybe uninvited) editors collaborating in real time, where they are in the document
* deltas, meaning that multiple people can be typing at once without bothering each other
* a LOT less data usage (again, because of deltas)

I know this looks like a toy, and it is, but it has some powerful dynamics, some of which I hinted at in https://highlighter.com/f7z.io/Collaborative-Document-jn40o0
