Most of us have a set of Preflight Options which we embed in the document. There are cases where the preflight error is intended and is not an error at all. LikeI highlight 'Non Proportional Scaling'.There are cases where I want un-proportional scaling of images. It would be nice that we could select these cases and mark them as non-errors. There are other cases like 'Bleed/Trim hazards which' are placed at the edge of a page on purpose.
In this way, once the error is chosen and selected as 'non-error' we will not get them marked as errors.
