Ross Piasecki and Susi Rathmann just finished a project where they 
got address books working in Celeste and bookmarks in Scamper.  (They 
tried to get tables working in Scamper, too, but ran into lots of 
problems.)

Their description of their work is at 
http://guzdial.cc.gatech.edu/squeakers/Celeste-Scamper-AddOns.pdf
The Scamper enhancements are at:

And the Celeste enhancements are at:

(These have been tested with Squeak 3.0, but I don't believe with all 
of Mike Rutenberg's latest enhancements to Celeste.)
