Adding Material to Cycles Material library in Material Library VX addon I want to add a material to the Cycles material library in the Material Library VX addon. But can't get it to work.

I can create a new category. What is not working is to insert a new material then. I press the add button, the status bar above tells me that the material is added. But it is not.

So what is the trick here? What is the exact procedure to add a material to the Cycles material library in the addon? What do i overlook here?
Got it working. It is possible. But a bit tricky. The filter category has to be off. Then it works. The steps are:

Turn filter categories off
Save Blend file with your new material.
Insert selected Material
Select material in the addon list
Switch to the category where you want to insert it.
Click at arrow button
Turn on filter categories
Refresh Library by clicking at the Filter Category button.
