I’ve also used windirstat (I think that’s what it was called) years ago on Windows and Disk Inventory X on MacOS graphically.
This seems like a nice in between that could replace both methods for me. I’ll have to try.
The GUI bunch of squares is really only useful when you can hover with a mouse and would be clunky in a TUI even if you could render it. And the FS structure isn’t immediately obvious, so I find myself wasting time wandering hovering over big files and globs of little ones.
I really like to avoid a mouse when I can unless it’s really useful.
