Right now, the profile page is a list of bullet points and a few
images. We can do better than that!

As discussed before I will probably implement a side bar on the
left.

The media pages could use a better design. There are loose ends
everywhere. For instance, the media description is hard to
distinguish from all the noise around it.

I'll work on this. This ticket is basically just to remind me. ;)

Right now, the slug is editable using the Edit form. That's great,
but you can also empty the field and it will still accept it.

Instead, it should show you an error (correct me if I'm wrong here)
saying something like "The slug can't be empty".
