I've always found it weird that a "function search" hasn't become more mainstream.

It's easy to implement without AI. Just make a big list of your functions, describe them verbosely, and give them a link - now let the user search for what they want to do and send them there.

I remember Rhino3d having this 10 years ago and it was amazing while all kinds of daws, editing programs, desks etc. would be a jungle to navigate or just have a "docs" or "help pdfs" - such a waste of time to look through.

In general this kind of navigation has been overlooked for decades.
