Using my cozy cloud to expose markdown (or maybe static HTML) pages would allow me to build a minimalist website, for example to expose a resume.
Yes, this would be a nice feature to have, we’ll think about it.
This would also allow sharing other files that depend on each other. Of course websites are the first thing that comes to mind, but there is also more obscure things like small package repositories, zsync files, metadata files (like a json describing how to use a file), 3d models with external textures, music playlists, etc.
Personally I am interested in hosting 3d models with json metadata and potentially external textures.
