Suggestion :
Please provide an option to see how the site will look to different users.
Viz. If I disable 'EDIT' to certain group of users I should be able to see the effect, that how the site will look/appear to them after disabling 'EDIT' option!
i.e. I should be able to confirm that the option is not available to them. (Right now, for this one need to ask the user, whether he/she can see the edit option or not ?)
