I can’t count anymore how many times I’ve been asked “when is the Dark Mode coming to CGE editor” 🙂
One answer is: It is already possible. We use LCL and our editor just follows your OS (Windows, GTK, …) theme. If you switch your system theme to something dark, then all your applications (including CGE) will become dark. There are small improvements to it in the physics PR too — I hope to finally finish and merge it this weekend!
Another answer is: We will get to the dark mode (in a cross-platform way, that can be activated specifically for CGE editor) one day, just because we have to 🙂 No matter how hard it may be with LCL.
Here’s a dark mode design by Adrianna Matejek. Thank you!
