First off I love the recent changes
Attached a JPG showing some layout tweaks for consideration.
List of Tweaks
1) Added the pager widget below the new Buttons widget.
2) Moved File Statistics widget up top next to the Interface Info widget.
3) Removed the "Uploaded By" line since its almost always the same as Author. Might not be a viable if the new "allow uploads" feature will result in this field being different than Author, or maybe the widget isn't easily customizable for different page templates.
4) Removed the word "Last" from the "Last Modified" label to save some space. Also changed the Date format to save a little more space.
5) Reordered the File Stats rows to line up more logically with the Interface Info rows.
6) Changed the "Pictures" box to allow text wrap-around.
This layout might result in some less-than-ideal line wraps inside the top section, but overall it should save some space while putting all the overview info up top. Allowing descriptions to wrap around the pictures box should save a bunch of scrolling
