Torsten, Offray, Trygve, Thanks for your suggestions for long term thinking.
In the meantime I need a workable solution for the coming weeks, I found the safer is to instruct the students how to operate with Playground to not lost their scripts. We design our teaching unit around one example and practical cases. The example part contains a Pharo script and the resulting DrGeo sketch. The practical case contains several DrGeo sketches and the students must write the Pharo scripts. They extrapolate from the script in the example. Therefore the work is incremental and before modifying any script they must rename the Page in the Playground. Some script will be reused in later units. I am pretty sure some, if not the majority, will forget to follow this protocol. Anyway we will see.
