I really love all the "modern" takes on classic tools by the Rust community.

I'm using eza (aka exa), aliased as ls, which has "tree" built in (aliased as lt), amongst others, as replacement for "ls" and it's one of my biggest production boosts in daily commandline use. Because eza has the tree built in, and the tree is also insanely fast, I won't be needing this tool - yet. Maybe one day the interactive mode will pull me over.

Congrats on releasing. And kudo's to how well you've released it: solid README, good description, good-looking gifs with exactly the right feature highlights

On interactive mode "ls tree" tools, an interesting one is broot.
