I have tried to 'borrow' certain sections of wp-admin/index.php with varying success.
It is, of course, my lack of PHP knowledge that causes it. Sorry.
I was able to take "Blog Stats" and put it in the sidebar, but not things like 'Incoming Links' and 'Comments' (I'd really like to have recent comments on the sidebar.)
Here is the site where I'm trying to do it.
Any help as to what to take, not take, from the wp-admin/index.php to get the "Incoming Links" and "Comments" would be great.
Edit: By the way, I'm using the Obsidian theme with sidebar, if that matters.
