If you are talking about appearance, you can customize it any way you like it.

If you do not like how it is "docked", You can do this: In the mixer to the right of "patches" tab the last is "folder" looking icon, clicking that will detach mixer, so it is free floating.

You can customize mixer to fit your needs. Size, what tracks it displays and much more. Play around with settings for 5-15 minutes, you should be able to figure it out.
