[Pharo-dev] confused about the "image opening session"

Hi I saw that we have a new cool feature that presents changes that would have been loaded but not save in the image. Now I got confused because several times I prompted with this list and I do not see how I ended up having it since I save my image and did not get crash (or idea that I lost changes). Is it me that do not understand correctly this feature? At the minimum it would be nice to have a little bit more explanation about what is happening. Because I imagine new guys coming and seeing this list without any further explanation could be confused. Stef
