This would surely help (in fact, I already do that), but it's only so helpful. Picture having a table with a hundred lines. Every odd line is grey, every even line is white. Every time I see that I have forgotten an entry between lines X and Y, I have to insert a line at the bottom and copy-paste all the connect south of the new entry. It's a hassle and inefficient.

Hell, I can't even highlight every second line in a table! That would ease things too.
