Now that I'm using an alternative "skin" for my admin-area, it has become obvious the Akismet-statistics block (in the right column) does not look the same as the other blocks, it is missing a div-tag. Put simply: all other blocks are embedded in a div, and the Akismet-block is not.
I would therefore like to request the embedding of the Akismet-block in a div.
The change is easy: add
<h3> on line 590 of akismet.php, and add
</h3> on line 596. It is that easy! :-)
