* Package Setup

* Appearance
|
||||
|
||||
Use =diredfl= for a colourful =dired= and =ns-auto-titlebar= for a macOS native title-bar look.
|
||||
** Mode Line
|
||||
|
||||
Show the column number in the mode line.

#+begin_src emacs-lisp

|

|

** Miscellaneous
|

|

I hate macOS scroll inertia. Scrolling in one window, switching to Emacs, and hitting control occasionally changes the text size and can even cause Emacs (and my window manager for some reason) to hang forcing me to force quit Emacs.

Configure =org-mode=. I use =~/org= as my =org= directory and hide emphasis markers because it's much easier to read that way. I enable =org-crypt= to allow reading and writing encrypted =org= files. I also replace bullets in bulleted lists with nicer looking icons. I configure faces to default to variable-width font, but switching to monospace where it is necessary. Finally, I use =visual-fill-column= to make =org= files display with a relatively narrow window centred in the frame.
