1. Download the minimal_theme.tres file of the latest theme version.
2. Open Editor Settings -> Interface -> Theme and choose the downloaded file in the Custom Theme field. You need to have Advanced Settings enabled to see it.
3. Click Save & Restart.

Minimal theme supports all editor settings. My recommendations are:

Editor Settings -> Interface -> Theme:

• Base Color: #252525
• Accent Color: #569eff
• Contrast: 0.25-0.3
• Icon Saturation: 2
• Corner Radius: 4-5

Editor Settings -> Interface -> Editor:

• Main Font: Inter

This theme was tested with Godot 4.3, 4.4 and 4.5.

• Support for editor settings is based on idea by Yuri Sizov described in this article.
• Dune scene used in the screenshots was made by Lander.
