The Shader Type Switcher lets you select the shader node editors types quickly and easily, with a pie menu.

I wrote this little Addon because I love the interactive ring menus in Blender and tools like Maya and Houdini.

I love Blenders shader editor but I got pre-fast fed up with constantly click on the Type drop-down and selecting the shader type.

So, I searched for a pie menu that does this, but I could find one, so I decided that I do it myself. :P
And it turned out that it was not too complicated.

So, the ShaderType switch is for you if you like to work in the shader editor a lot, and if you work in the world in object shader type and switching back and for a lot. And if you prefer to work with pie menus, instead of shortcuts of the UI buttons.
