Love the simplicity of your site, by the way.
It's a third iteration of it.
For a few years I had following setup: 1. keep files in dropbox 2. sync them and publish automatically using montaigne.io
Now I switched and instead of Dropbox I use Apple Notes. Because it's easier to write, and mobile UI is better and it supports tables and images out of the box.
Not possible for now to change default name though! You can either create new site with new name and delete this one (or again, email me).
Agree about FAQ! I started making FAQ https://docs.montaigne.io/faq but didn't finish it yet.
custom domain support is there. That is how I ran my own site anyway. It just that it's a bit manual process for now. But I'll improve it.
does it make sense? can provide more details.
Apple Notes is a gem.
