The history can be a bit strange.
When I open the Crop and Rotate module, do a rotation, then do a crop (or reverse the order), the history has 2 entries but compressing the history merges the 2 entries. This is good as it has evaluated all the “versions” of the module and combined them into 1.
However, when I open a module, make a change, go to another module make a change, go back to the first module and turn it off, then compress the history, the off module still appears in the history. If this is the last instance of that module, then the off version should not be there.
My feature request is that, if the Off version of a module is the last version of that module, then the module shouldn’t be listed in the compressed history (I don’t mind it appearing in the uncompressed history but I don’t think it should be present in compressed history.)
