If the right-side lists remain, can you make them show the last 50 posts instead of only the last 7?
Better, remove them (freeing up valuable screen width to see posts better) and add two new entries to the "Recent Posts" dropdown: "All Forums" and "All Blogs". The date-sorted lists there contain very useful info, who posted, when, what forum, etc. Probably the 50 most recent posts would be sufficient.
Removing the left-side "ID" column was a good idea, and posts are MUCH more readable now.
