You can filter by Feature in the Content Management. Simply select the feature, check the "Filter by Feature" checkbox and click Find.
Not sure I know what you are calling the "Control Panel" but you can use the Site Statistics feature to see statistical info on the users of your site. You will have to add the Site Statistics feature to a page, and, if you do not want anyone to see it, change the "View This Page" permissions in the settings of that particular page. You can also restrict who can view particular features on a page by using the security settings of the individual feature.
I do agree that we need some sorting functionality added to the blog. Can you tell me what a DLE engine is?
