Restriction only by Group, not by capabilities ! Why ?

Hi,

I just buy the plugin because I need to have a Capabilities restriction (and not Group restriction) for my post categories and pages, and when I read the description of this plugin I was like “Woaw I need it”.

But after installation, when I go to the categories management, I can just choose Group for the restriction, not Capabilities.

Can you help me ? What is the problem ?
