Can I ask what happened to your prediction that Hugo “will receive a perfectly structured and searchable documentation site” in 2021?
If you or other people are still working on this, then it’s best we as community remain patient, rather than intervene with ongoing work and suggest a change of documentation framework.
Nothing will be worse than people wanting the docs to be written with framework B when most of the work is already done with framework A.
We’re not in a hurry and appreciate everything the maintainers, developers, and writers do.
