Org Mode
#
I used to respect the 80 column limit, but why waste all the space when it can be dynamic. In this way all of the available screen space is utilized.
(add-hook 'org-mode-hook 'visual-line-mode)
Enable "fake" indentation in org-mode, in other words, add indentation using overlays, but on disk the buffer is not indented.
(add-hook 'org-mode-hook 'org-indent-mode)Increase the size of headings, in my personal opinion this makes the headings stand out a bit more and therefore easier to read.

To go back to the previous mark, very useful with Org Roam.

Enable tangle on save, big thanks to Diego Zamboni for his amazing booklet about Literate Configuration.

After executing a source code block with org-babel, redisplay inline images, this speeds up the REPL-like workflow a lot.
(add-hook 'org-babel-after-execute-hook 'org-redisplay-inline-images)Enable additional babel languages.

For previews, create SVGs and not PNGs or something, use the dvisvgm-lua command.
(setq org-preview-latex-default-process 'dvisvgm)
Actually define dvisvgm-lua.

To support non-breakable whitespace, create a new org-entity.
(add-to-list 'org-entities
'("space" "~" nil " " " " " " " "))Enable fontification for inline LaTeX blocks which convieniently also makes in fixed-width.
(setq org-highlight-latex-and-related '(native script entities))Sliced Previews
Normally a LaTeX preview is just one huge image which makes Emacs really jumpy and makes writing prose a really unpleasant experience. With these two functions, that's fixed. They work using mainly text properties (overlays are still involved but only one per preview, max two) so it should be fast still.
