Interesting, but what does this solve what Bookstack does not solve? I mean sure, it looks nice and hacky and all that. But if i am going to host some note thingy, https://www.bookstackapp.com/ is right there and apparently the dev nowadays lives from the thing (which is nice i guess). Not to belittle your project in anyway, even if something like your thing would exist exactly as that its still commendable but i am already running Bookstack and this seems to add anything to any use case i could think off.
