Somewhat related: can fish shell do something like this? https://github.com/hchbaw/auto-fu.zsh
On the fly display of all the options. If so, to what extend? Some commands don't give autocomplete upon tab. Is there a way to fix that?

Showing everything as you type sounds neat, but in practice it's jarring to have your screen fill up the second you press a key. fish operates on the UI principle of progressive disclosure: be helpful but not overwhelming. That's why it only shows one.
fish knows how to parse man pages to extract options, so fish can tab-complete options even for commands that don't have explicit completions. It's surprising that nobody else seems to have tried this.
ridiculous_fish, we still use `complete` all over the place for completions don't we. In Fisherman there is a nice little AWK script, still far from perfect that attempts to do a similar thing, parsing a utility's usage help.
