+* General configuration
+** User Interface
+
+Clean up Emacs' user interface, make it more minimal. Improve scrolling.
+
+#+begin_src emacs-lisp
+
+  (setq mouse-wheel-scroll-amount '(3 ((shift) . 1))) ;; one line at a time
+  (setq mouse-wheel-progressive-speed nil) ;; don't accelerate scrolling
+  (setq mouse-wheel-follow-mouse 't) ;; scroll window under mouse
+  (setq scroll-step 1) ;; keyboard scroll one line at a time
+  (setq use-dialog-box nil) ;; Disable dialog boxes since they weren't working in Mac OSX

+Set frame transparency (and maximize windows by default).

+Set line spacing.

+  (setq line-spacing 0.03)
+
+#+end_src
+
+Enable line numbers and customize their format (e.g.: relative numbers).
+Also set the width of the line number column.

+  ;; Enable line numbers for some modes

+** Theme
+
+These days I bounce around between themes included with [[https://github.com/hlissner/emacs-doom-themes][DOOM Themes]] since they're
+well-designed and integrate with a lot of Emacs packages.
+
+A nice gallery of Emacs themes can be found at https://emacsthemes.com/.
+
+Alternate themes:

+The [[https://github.com/myrjola/diminish.el][diminish]] package hides pesky minor modes from the modelines.
