Enhance The Mark All functionality

[Raven]

It would be a real help if you could maybe mark/highlight in the document selector window, all the files that had bookmarked lines. In other words, you might have 100 files in the document window and you do a Mark All in All Documents. Maybe only 10 of those documents were marked but you have to check each one. If you would mark them, then we know right away which files to look for.
