+This org file is tangled to [[./init.el][init.el]] and constitutes my Emacs
+configuration. =straight.el=, =use-package=, =general.el=, =exwm=,
+=org-mode=, and =magit= are some of the awesome packages powering my
+Emacs setup.

-** Backups
+** Better =$PATH= handling
+
+Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
+in my shell.
+
+#+begin_src emacs-lisp
+(use-package exec-path-from-shell
+  :defer 1
+  :init
+  (setq exec-path-from-shell-check-startup-files nil)

+  ;; while we're at it, let's fix access to our running ssh-agent
+  (exec-path-from-shell-copy-env "SSH_AGENT_PID")
+  (exec-path-from-shell-copy-env "SSH_AUTH_SOCK"))
+#+end_src
+
+** Server
+
+Start server if not already running. Alternatively, can be done by
+issuing =emacs --daemon= in the terminal, which can be automated with
+a systemd service or using =brew services start emacs= on macOS. I use
+Emacs as my window manager (via =exwm=), so I always start Emacs on
+login; so starting the server from inside Emacs is good enough for me.
+
+See [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Emacs-Server.html#Emacs-Server][Using Emacs as a Server]].

+*** Disable disabled commands
+
+Emacs disables some commands by default that could persumably be
+confusing for novice users. Let's disable that.
+
+#+begin_src emacs-lisp
+(setq disabled-command-function nil)
+#+end_src
+
+*** Kill-ring
+
+Save what I copy into clipboard from other applications into Emacs'
+kill-ring, which would allow me to still be able to easily access it
+in case I kill (cut or copy) something else inside Emacs before
+yanking (pasting) what I'd originally intended to.

+Let's customize the =*scratch*= buffer a bit. First off, I don't need
+the default hint.
+
+#+begin_src emacs-lisp
+(setq initial-scratch-message "")
+#+end_src
+
+Also, let's use Text mode as the major mode, in case I want to
+customize it (=*scratch*='s default major mode, Fundamental mode,
+can't really be customized).
+
+#+begin_src emacs-lisp
+(setq initial-major-mode 'text-mode)
+#+end_src
+
+*** More useful frame titles
+
+Show either the file name or the buffer name (in case the buffer isn't
+visiting a file). Borrowed from Emacs Prelude.

+*** Backups

 
 Emacs' default backup settings aren't that great. Let's use more
 sensible options. See documentation for the ~make-backup-file~
