Motivation

I find myself disliking a majority of column-based terminal file managers. The reason for that is - when I need to copy/move some files across nested subdirectories, I constantly lose context of where I am currently, because columns always go left and right. Even though those file managers are really mature and loaded with features (e.g. ranger, lf, xplr, nnn), it's uneasy for me to perform simple tasks.

I like how broot renders the ui, but I guess that it's mainly usable for exploring a file tree, but not manipulating it (at least I found it this way, when I had to type a target directory for move).

That's why I'm writing my own simple tool for simple use cases. It's currently lacking a bunch of features (see todo list below), but the fundamentals are here.
