[The style does not work well since GMail handle themes]

This is a skin for GMail 2.
It is a minimalist skin with a monospace typeface.
It is almost finished and should already be fully usable.
I strongly suggest using the following styles with it:
hide gmail add and extends mail column in gmailV2
Gmail - Hide Invites

You may also enjoy other minimalist styles I made (and that work very well with this one):
GMail - 2 Remove lines from the main menu
GMail 2 Remove the selectors (top and bottom)
GMail 2 Remove the star system
GMail2 Remove Quick Contacts Info Cards
