Overall I think the admin control panel has a good interface. Imho, you can still still improve on it to make it easier for admins or moderators to locate stuff. Anyway, I want to start off with the add-on list there. I love wordpress and how their admin control panel works. Their plug-in list is simply amazing. Under each plug-in, you have a brief description of what it does. It is especially important for people like who don't visit that page often. I tend to forget what each does and the description reminds me. Also, each plugin has a 'settings' link attached to it. I don't have to go to another place and locate where the settings link is. Just to make it clearer for you here are the screenshots my xf add-ons list and my wp plug-ins list. Give add-on developers a great platform to work on and so much more can be done with xf. Apple appstore is a great example. If someone's already posted a similar suggestion... oops.
