Would be nice to have the ability to check a user's specific permission (ex: if they have Read level access on a particular entity). An example would be if you have a formula on Account that finds the sum of all Invoices and displays the total as a form notification on Account. If a user has access to Accounts and not Invoices, this would cause an error. Rather than hard-code the security roles into the formula using IsUserInSecurityRoles, we could check if the user first has Read permissions on Invoices, and if so, execute the formula.
