Admin Bar & Dashboard Access Control

I've used 2 plugins before for this stuff. This excellent little plugin makes it really easy, all in 1 plugin. Does just what it needs to and does it well.

My only complaint: it adds a new sidebar item in the Admin. It really should have it's settings under Settings or Tools sections. Only plugins with multiple pages of settings, and that need to be accessed regularly, should add more height to my sidebar. If that gets fixed, I'll change my review to 5 stars! I know it's a bit nit-picky of a complaint. I guess it shows how good this little plugin is, when that's the only thing wrong.

Works great, does the work of 2 plugins elegantly!
