Praise: First of all, this suggestion provides a handy and welcome opportunity to deliver a paean to @AmberV and everyone else who takes care of the manual, because it is comprehensive, it is clear and it is presented beautifully. I have done a fair bit of technical writing over the years, and I can honestly say I never produced anything anywhere near this good, but I wish I had.
Suggestion: That said, there is so much in the manual, how about L&L training a custom Large Language Model on the manual (and maybe even the comments in the fora) so that natural language questions can be used to find the information. I would have thought this pretty straightforward these days, especially given the tech experience behind the scenes and if it were hosted here it would be so useful.
Rationale: keywords are fine for really specific topics; key phrases are OK-ish for things like named UI elements (e.g. “Separator between sections”) but beyond that, one can rarely find a good phrase, and the hits on individual words are too numerous: LLM’s take care of auto-synonymising and effectively performing semantic searches.
