[suggestion] Add Remove color marks

[Jensen Head]

Print registration in layouts for printing houses are vector objects that are quite labor-intensive to remove from PDF when there are many pages in the document, and the pages contain other content in the shapes format. And the editor does not support the selection frame directions (1, 2). At the same time, these marks are standard both in form and in location, and they can be removed automatically. At least, I have encountered this functionality in PDF editors.
