Features

As well as recolouring Obsidian's interface, the Material Ocean theme comes with a number of layout and typography tweaks and quality of life editor improvements.

• Element spacing, sizing and positioning has been adjusted for a more consistent editing experience.
• The window minimise/maximise/close button icons are replaced by icons from the Lucide icons toolkit, matching the smoother and more rounded designs of the other in-app icons
• The top-left sidebar toggle button has been accented and the surrounding borders simplified and rounded for a more aesthetic design.
• Long code lines overflow and are scrolled horizontally instead of being wrapped onto the next line. In reading mode, whole code blocks can be scrolled. In source mode, individual lines must be scrolled due to architectural limitations.
• Images are (slightly) rounded, headings are underlined and callout arrows are right-aligned.
• Checkboxes are circular and completed tasks are greyed out instead of crossed out. The following alternative checkbox styles have been added:
  • - [/] represents an incomplete task with a half-filled circle.
  • - [-] represents a cancelled task by crossing it out.

Supported Plugins

I did not create the original Material Ocean colour palette. Full credit for that goes to the original Material Theme. I have selected colours from the original theme, adjusted them, and added additional colours for the purposes of adapting the theme to work with other apps e.g. Obsidian and Notion.
