Sometimes, you do not want \version[temporary]. In those cases, I usually 
use

\overfullrule5\points

This can also be incorporated in the \version command,


\unprotect
\def\doversion[#1]%
   {\chardef\conceptmode\zerocount
    \overfullrule\zeropoint
    \processaction % \v!final=>
      [#1]
      [  \v!concept=>\chardef\conceptmode\plusone,  % simple banner
            \v!file=>\chardef\conceptmode\plustwo,  % full banner
       \v!temporary=>\chardef\conceptmode\plusthree % full banner plus
                     \overfullrule5\points,         % info in the margin
              draft=>%\chardef\conceptmode\plusfour
                     \overfullrule5\points]}

\protect

and then one can use \version[draft].
