Hidden panels
Bruno,
You can "hide" them if that is what you want.
But, you can do even more, you can do what I did - and that is make a picture frame of panels on each edge of the screen, and through panel properties, select a color, and then dial DOWN the transparency (i.e. make it more transparent).
Thus when you maximize a window, some of your screen wallpaper "peeks" out from under the window. In my case, the bottom, left and right hand panels are transparent, but the top one is not.
The best part is using a nice wallpaper for your screen. and that choice is left to your imagination.
My imagination led me to this photo of Alicia Keys taken this past 7th, when she was in South Africa for the FIFA World Cup. Every good looking woman MUST have that `one` "little black dress", and DOES IT LOOK GOOD on her. It might still be on her site (aliciakeys.com).
The caption added to that photo is taken from one of her song titles - `sure looks good to me`.
