Thanks for finding the letter "m" bug, an embarrassing one for sure! Also thanks for bringing up the issue of select all on mobile, I'll think about how to improve that. Adding a tag line for each module is also a good idea.

Interesting that you mentioned fine-grained security. Currently block-level access control can be achieved with block embeds, but it has to be done one by one. I looked into enforcing access based on a query for page embeds (so allowing only portions of the page), it turned out to be non-trivial! Might try to implement in the future.

Thanks for breaking down the different levels of self-hosting. I'll keep them in mind.
