I've written a plugin called Enhanced post management that adds three minor features to the Manage Posts administration page:
- Adds the day of the week to the post times (The seconds are removed to make room. Do you really need to know whether you posted at 2:20:17 or 2:20:41?)
- Turns the post titles into links to view the posts, like WordPress 1.2 used to have
- Colors the titles of future posts red (or the style of your choice)
See the link above for complete details.
