This sounds extremely similar to our proposal for the Undo system of Gimp-2.0, where we will record changes to the context together with the Undo information. The question is: do we really want to make this change now? This won't be trivial and is likely to introduce new bugs. We could have a 1.2 release this month, or we start to hack the undo system now and end up doing similar changes until the end of the year. Is this change worth that effort? Salut, Sven
