Options to change the skin of the UI. Options to change the UI for basic and advanced users.

I would like to be able to change the look of the UI to match my current windows theme.

Options for a simple UI for beginning and basic users and keeping the current UI for advanced users.
Everything in the current set up is for advanced users and can be very overwhelming. I am a new user to the product and want to make back up copies of my DVD collection. All of the features and functions are confusing to me.
