A good resource for discovering DarqUI features is the DarqUI Portal
page. Also, if you click Help on the Start menu in-game, there is a DarqUI Help tab with quite a bit of information about the various components and the utility. Unfortunately I don't have a screenshot that shows everything at once. If you're having trouble with something in particular, this is the place to ask about it.
