awesome. Exactly what I was looking for, and if you can add couple more things, then donation coming your way :-)
In the current version, it appears two menu items still show up, with no apparent option to hide for "contributors" level (etc.),
which are top right "screen options" and "help" ...
Since those might only confuse a user since the help menu shows explanation of all the things not actually there with open invitation to leave site for help.
Easy fix: hide them. Super cool: option to redirect help to a custom help screen, or edit the text shown in drop-down.
