auto collapse menus (tool panel 'T' and 'N' panel)

I run Blender on a netbook, so resolution is 1366x768.
Adding an auto collapse function to the tool panel, and ‘N’ panel will ease the pain of scrolling up and down the menus.
Maybe an option in preferences, so it is an option.

Simply close all the panels in the shelves and use CTRL+CLICK on a header to open only one panel at a time. The rest will automatically close.
