Shameless plug: https://github.com/candidtim/f2-commander

I've been working on "F2 Commander" on and off for a while now. At first, I wanted a TUI to view the contents of cloud storage buckets (GCS, S3, etc.), but it quickly evolved into an orthodox file manager. The funny thing is, the first version was in Common Lisp, but then I discovered Textual and was instantly sold on it - it's really fun to work with. The app scratches my itch, and although most of the time I myself prefer just using the regular command line, I open it up when I need to quickly navigate or move some files in a complex directory tree.
