I noticed you're not using some of the built-in godot icons. I highly recommend you check them out as some of your placeholder icons can easily be replaced with native godot icons. Would go a long way to making MTerrain look more polished.
I also made a logo and a brush icon if you want to use it. I can make a pull request with the SVGs if you want me to.
You really need a way to be contacted more easily by the way.
