I too prefer fizzy history. It's like Sodastream for your shell!

Skim [0] is a nice alternative to fzf [1], mainly for the fact you can call additional commands dynamically like so [2]:

    sk --ansi -i -c 'rg --color=always --line-number "{}"'

[0] https://github.com/lotabout/skim [1] https://github.com/lotabout/skim#difference-to-fzf [2] https://github.com/lotabout/skim#interactive-mode

Would that correspond to piping the output of the additional command to fzf?

fzf's great. I use it for a quick/easy git branch menu, complete with preview of recent history of each branch: https://pastebin.com/R91bP2qa

I like fd more. fish already has autocomplete.
