From everything I've done with SCDP and SCCP it's my under standing that the themes are the real heart of the software. You can create your own themes that are just altered existing ones. The SCDP is used to design your shops look and feel while SCCP decides how it will interact with the user. For your category detail properties click the advance tab over to the right hand side panel. It looks like from your video that you need to grab the window pane and drag it left to expose the properties box.
Edit
Ok I know what your after now. In SCCP click on you shop at the top. In shop setting click pages. Go down to the categories section and check the box's to make it look the way you like.
