Then I must add, a very well done to you on an awesome add on. Your plugin works at its best in conjunction with a capabilities plugin, like Members or User Role Editor, which handle the permissions on accessing certain pages.
Your plugin comes into play when hiding the comments admin tab when it's connected to the edit post capability and not moderate comments capability, which is not quite neat when you don't want a user to see the admin tab but still edit posts. Admin menu editor also gives the nice "You don't have sufficient permissions..." message when restricting a user from seeing a page, so this is awesome - and like you said, Toolbar editor is an add on, and relies on Admin menu editor, so if you hide the comments admin tab, you might want to hide the comments from the Toolbar for that user as well, as once it's hidden with Admin menu editor, you get the "You don't have sufficient permissions..." so it defeats the purpose of being in the toolbar.
I must say Money well spent!
