I imagine most people who live in the terminal are using their editor's file manager for this. How does this compare to neovim+nvim_tree for example? Seems like a subset of what a modern neovim setup can do.
That's absolutely true for people who want to interact with their projects using their editors exclusively! Personally, I like using both my shell and neovim for stuff like this, and I felt like there was no great option for me on the shell-end of things.
The usefulness of a tool like this is definitely completely dependent on a person's workflow.
