In order of complexity:
- set (leader "dd") to ~dired~ rather than ~dired-jump~, because I
think it's better to have an option to choose directory
- +dired/maybe-frame -> dired-other-frame (just use another frame always)
- dired-omit-mode config:
- When ~dired-hide-details-mode~ is on, hide all dot(files/directories)
- When ~dired-hide-details-mode~ is off, show all files (turn off ~dired-omit-mode~)
- This is achieved by hooking ~+dired/omit-files~ (which does the
above) to ~dired-hide-details-mode-hook~
