1-Pixel-Border

[ghost]

Please can you add an vertical optional thin borders left left left left right with an chooseable color?

For my eyes it is a little bit hard to find the outer borders for better viewing. But only to the sides :-)

Oh no, it might be more useful if you add a 1-Pixel-wide empty colored taskwindow as border on the sides and between. This way it will be centered or aligned correct :-)
