One convenient feature could be to the add the auto completion of kopia commands in shell. ex: with bash shell on debian, when typing "sudo apt-get ", a tab key press triggers the available commands. Typing "kopia repository " could list the commands listed in “kopia repository --help”, and “kopia rep” could auto complete the command to “kopia repository”.
Note it’s not activated by default because the kingpin library has some bugs which make this annoying - most importantly the filename completion is not actually working (only commands and flags are completed, but you have to type path names unaided). It would be awesome if somebody could help fix this upstream.
