Custom Editors for Shaders?

After developing a series of very large shaders, I feel I am in need of a custom inspector for them as they take up far too much room.
I like the look of the Standard Shader editor with the small texture boxes, but have no idea where to start, not very many people do this to shaders but I feel like I should probably have them.

Does anyone know how to write custom inspectors for shaders?

 

You can define a custom editor for a shader by deriving from ShaderGUI, and adding

Code (csharp):

1.  
2. Shader "ShaderName"
3. {
4.     [...]
5.     CustomEditor "NameOfCustomGUI"
6. }
7.  

to the shader itself.

I have little experience with this myself, but it looks like you can use standard EditorGUI calls in this.
Check Unity's built-in shaders for examples.
Cheers!
