Hey there,

I've just gotten the app to go along my Godot project development, and I've made a theme consistent with the one I use in Godot engine.

Here it is if anyone is interested, with two subtly different versions (order of elevation colors switched):

1. godot_pro_red.json
2. godot_pro_red_inverted.json

Extra:
And there's also this Windows inspired one, just white, light blue and blue: (Not dark mode)

1. cloudy_blue.json
