1) Listing Page
There's an option for this to show up as a page under Tools.. but even when enabled, I can't find it. I searched the code for add_submenu_page and couldn't find anything, so I'm confused. I love the dashboard as a quick way to view activity, but would love to see a lot more items on a larger page format
2) Settings Form
Have you thought about putting the Settings form on its own screen? It would help control user access to it. You could consider setting a special capability to see it for compatibility with something like the Members plugin, or even if it uses manage_options, gives us the ability to hide just that section.
