+* Blocks, Parentheses and Formatting Oh My!
+
+** Parentheses, and Structural Editing
+
+Sometimes if I delete a parenthesis out of hand I spend the next minute or two
+kicking myself as I count the parentheses here and there.  Well no more!  With
+[[https://shaunlebron.github.io/parinfer/][Parinfer]] structural editing, and taming parentheses becomes a
+breeze.
+
+#+begin_src emacs-lisp
+(use-package parinfer-rust-mode
+  :ensure t
+  :init
+  (setq parinfer-rust-auto-download t)
+  :hook (emacs-lisp-mode . parinfer-rust-mode))
+#+end_src
+
+I also have =smart-parens= for parentheses matching in modes where =parinfer= would
+be overkill.
+
+#+begin_src  emacs-lisp
+(use-package smartparens
+  :ensure t
+  :hook (prog-mode text-mode markdown-mode)
+  :config
+  (require 'smartparens-config))
+#+end_src
+
+Might as well highlight the parentheses to make them easier to spot.
+
+#+begin_src emacs-lisp
+(use-package highlight-parentheses
+  :ensure t
+  :hook
+  (prog-mode . highlight-parentheses-mode))

+
+** Indentation Level
+
+#+begin_src emacs-lisp
+;; Indent guides
+(use-package highlight-indent-guides
+  :defer t
+  :hook (prog-mode . highlight-indent-guides-mode))

+** List, and String Improvements
