I've added the new PI models' SDF lights to the SDF overview screen, as well as including which snap file is loaded onto the SDF overview. I've also done a bit of rearranging. 
/opt/rtcds/userapps/release/sys/h1/medm/SDF_OVERVIEW.adl
has been committed to the svn repo.

Attached is a screen shot of the new hotness.
