Hi! I created a GitHub repo with some Yazi flavors packaged with Nix to be used with Home-Manager. It offers all the flavors found in awesome-yazi and a few more. Feel free to take a look at it here, and make a PR adding other flavors.
Beware that those flavors require Yazi >= 0.4.0, so if you’re using Nixpkgs Stable you’ll have to backport Yazi.
