Add the ability to designate specific tables and columns as "report" tables/columns
Right now the Report Editor allows users to select any table and any column on that table. In reality, there are really only a handful of tables and on those tables, only a limited set of columns that are really needed for reporting. Many tables and columns are used for system purposes. By allowing this designation, it would provide a simpler interface to anyone writing reports.

I think this has a solution already... Check out Garrick's Blog post: http://community.servicenow.com/blog/garrick/simplifying-reporting-rightly-understood

Even better would be to allow the use of certain columns visible for selection in the users personalize list view (user gear icon, not admin). This would include Admin designating certain extended columns as available (caller.phone).
