This package implements a modern style for your Org buffers using font locking and text properties. The package styles headlines, keywords, tables and source blocks. The styling is configurable, you can enable, disable or modify the style of each syntax element individually via the org-modern customization group.

The screenshots shows example.org with org-modern-mode turned on and off. The elegant theme featured in the screenshot is modus-operandi.

Since this package adjusts text styling, it depends on your font settings. You should ensure that your variable-pitch and fixed-pitch fonts combine harmonically and have approximately the same height. As default font, I recommend variants of the Iosevka font, e.g., Iosevka Term Curly. org-modern-mode tries to adjust the tag label display based on the value of line-spacing. This looks best if line-spacing has a value between 0.1 and 0.4 in the Org buffer.

The package is available on GNU ELPA and MELPA. You can install the package with package-install. Then org-modern can be enabled manually in an Org buffer by invoking M-x org-modern-mode. In order to enable org-modern for all your Org buffers, add org-modern-mode to the Org mode hooks.

;; Option 1: Per buffer
(add-hook 'org-mode-hook #'org-modern-mode)
(add-hook 'org-agenda-finalize-hook #'org-modern-agenda)

;; Option 2: Globally
(with-eval-after-load 'org (global-org-modern-mode))

Try the following more extensive setup in emacs -Q to reproduce the looks of the screenshot above.

(global-org-modern-mode)

• org-indent-mode is not compatible with the block prettification in the fringe. If org-indent-mode is enabled, org-modern will disable the block prettification.
• org-num-mode interferes with the org-modern prettification of TODO keywords.
• visual-wrap-prefix-mode relies on the wrap-prefix text property which is also used by org-modern.

The tag style of org-modern is inspired by Nicholas Rougier’s svg-tag-mode. In contrast to svg-tag-mode, the package org-modern avoids images and uses more efficient Emacs box text properties. By only styling the text via text properties, the styled text, e.g., dates or tags stay editable and are easy to interact with.

The approach used here restricts the flexibility (e.g., no rounded corners) and creates dependence on the size and alignment of the font. Combining org-modern-mode with svg-tag-mode is possible. You can use SVG tags and use the table and block styling from org-modern. If you are interested in further tweaks, Emacs comes with the builtin prettify-symbols-mode which can be used for individual styling of custom keywords.

Alternatives are the older org-superstar and org-bullets packages, which are more limited and mainly adjust headlines and lists. org-superstar relies on character composition, while org-modern uses text properties, which are considered more future-proof. Note that org-modern is a full replacement for both org-superstar and org-bullets. You can disable styling of certain elements, e.g., org-modern-timestamp, if you only want to use the subset of org-modern equivalent to org-superstar.
