Thanks for the explanation Christophe. The tree might be a good idea.

I mean that when I « save as », I do it mainly because I know my next code evaluation could crash the image ^^. So basically, what I need is to save a copy of the image (timestamped eventually) but still using the original one. **So later, in case of crash, I can roll back to a previous backup**. That is far easier to implement I guess than the tree and that would be **very** useful to me at least ;-) Not sure, but I also think we should enforce by default to share the iceberg repo. For most people, top save sandwich, etc, it seems a better direction to me. This is optional right now but can’t we change the default ? Cheers, Cédrick > > Cheers, > Christophe
