There's a lot of these pickers and they are indeed similar. I've been using https://github.com/jhawthorn/fzy since it's not fullscreen and has a really good matching algorithm.

fzy is cool and probably underrated. It's the preferred fuzzy utility for file manager nnn too.

i loooove syncthing. something i set up recently is a folder called .home_sync to sync my dotfiles between computers. I have a bash script that sets up the symlinks and then version control turned on for the syncthing folder so i can have a record of any changes if I need to revert something

I've tried both Skim and fzf, and in my experience fzf has a much better fuzzy matching algorithm so that's what I'd recommend using. Plus it supports true color configuration fwiw.
