Honestly, these are actually both features I would like to see. In the actual case mentioned above, I would indeed like to be able to add an ignore filter for UserData.SID changes. But in reference to a previous ticket (Hide changes in model), I would also like the ability to individually pick and choose blocks/systems to hide, or as you say “acknowledge and remove from report”. Are either or both of these things feasible additions to DiffPlug?
P.S. The 3rd option mentioned where I specifically ignore for a string may be too specific, I think I would just go with a blanket ignore on any differing params/properties.
