There are no tutorials for general options in the UI, as that is entirely up to the user, in this case you. How i have my options set as well as the actual theme i use is probably very different to you, so if i was to make a tutorial with my settings, it would be completely irrelevant to you. We have options so you can make it look how YOU want it to, we cant make a tutorial for that as only you know what you want. Just mess with the settings, they are pretty self exoplanetary as to what they are going to change.
