Post title: Removing duplicates + deleting entries with older timestamps

And another one I have been wondering about: Removing duplicates. I know we already have:

Edit > Remove duplicates from database, but no matter what I do, I still seem to be left with tons of duplicates after running it. Even if I run it with only two columns displayed.

And on a related note: it would be great if I could clean the database of updates over time, by deleting entries with older timestamps.
