I see that this topic was already brought up but in the feature request forum and unfortunately the reply (that this was supported now) didn't help me.
I'm not able to see categories that I should (based on my “role” as administrator) in my categories listing in the sidebar. Only categories with public posts (visible to everyone) are appearing.
I may be missing a setting but I'd have thought even the default settings would allow admins to view all categories when logged in.
On a side note, I hate to complain but this plugin is not the most user friendly one I've run across. While I'm sure it has many capabilities and is very complex from a coding point of view I'd love to see it much more straightforward (simpler) from a user stand point. To be honest I've only spent the last several hours trying to better understand it because disclose secret isn't compatible w/ v 2.7 and I'm unaware of any alternatives.
I'd love to see a dumbed down version for us simple folk
