Fzf: A command-line fuzzy finder

Combining fzf with ripgrep[1] as a search tool has absolutely changed file search on my computer. ripgrep is much faster than your typical "find", but it eats up CPU. That being said, the preview window in combination with being able to browse large directories a breeze.
On that note, skim is an alternative to fzf written in Rust -- https://github.com/lotabout/skim
This is a perfect addition for the fish shell, to fill the incremental reverse search gap. Highly recommend.
One of the most useful shell plugins IMO.
