Hi matthew I'm not sure the fixes of Gary and Simon were overrides. But indeed this would be cool to have.

I just rewrote the image snapshotting code, so I think I know what to do. The diff tool takes two snapshots and compares them. Image snapshots are built from the MethodReferences passed in from PackageInfo. To make a diff with overrides, the snapshot will have to additionally snapshot any methods or classes that appear in the compared package.

[Pharo-project] Polymorph

Just to let you know there are some newer versions on SqueakSource. Start of work on a "Watery 2" theme (more spotted cat like :-) ) using CompositeFillStyles with form-based graphics. A few other improvements too, check the version notes. Regards, Gary.
