It will be cool if the solidworks supports the callouts from some features other than bent lines, holes, such as extrude cut, chamfer, fillet or any features. If  it works, we can callout some welding notes, sandblasting notes, grinding notes when generating drawings. of course, its callouts should support formatted notes or custom notes or even some 2-D blocks from CAD files. I dream to get this on next Solidworks version.
