User roles and capabilities

The devs are working on some revisions regarding roles and capabilities. See:

https://trac.www.ads-software.com/ticket/2787
and
https://trac.www.ads-software.com/ticket/2775

I know you don’t want to use plugins, but there is a plugin that allows the creation of new roles and then a plugin to restricut category access by role.

“Limit Categories” (https://www.asymptomatic.net/wp-hacks)

and

“Role Manager” (https://redalt.com/wiki/Role+Manager)
