OK - I'll post this tip here in case anyone else wants the same thing.
I had a couple of clients who didn't like the way 6.2 highlights the row on the postlist page.
If you leave the new classes out, you'll get some black boxes in some browsers. Not pretty.
So be sure and use the newlighttable, newdarktable and newsubjecttable classes, but set them the same as their non-new counterparts.
Set newlighttable identical to lighttable
Set newdarktable identical to darktable
Set newsubjecttable identical to subjecttable
I can't really understand why some people wouldn't want the row to glow.. but what do I know. LOL
A variation of this is to set the colors the same.... but text bold if they are new.
