Script Summary: Hides the Netvibes top bar (including tabs, search area, add content) and bottom and allows you to toggle them back on using an icon :)
This is a totally re-worked version of the Maximise Netvibes code by Joaquin Moran. I found it didn't work too well and decided to rewrite it to remove more of the top bar area. This is as minimalist as I wanted it to be; the icon allows you to toggle the bar back on for if you need to adjust settings or access your tabs.
If you like your list of tabs (I have some but don't use them often) then just edit the source and comment out the relevant lines.. there are only 2 places to comment it out.
