If you like ncdu, you might also like dua[0]. You can run `dua i` to get an interface similar to ncdu, and can also run `dua` to list file sizes in the current directory, similar to `du`. Or `dua filename` to get the size of a given file.
Painpoints are that there seems to be no progress bar in interactive mode, the ui is (imho) ugly/unintuitive (for instance the usage bar seems to be relative? and the shortcuts look like glyphs) and there are functions missing (like exclude patterns, you can exclude dirs though!).
So it won't replace ncdu, but if it get a interactive progressbar maybe it will be on all my machines (with arch)
