v 0.2, updated August 18th, 2012 to support the CSS changes that Microsoft made to the CSS. If you want to add a background pattern to the topbar and selected items in the Folder and Message lists, you can add this code, making sure to include a URL to the desired image file:

.t_hdbg {
background-image: url('IMAGE_URL');
}

.t_sel {
background-image: url('IMAGE_URL');
}

.MenuItemSelected, .LeftNavBasic li.ItemSelected a, li.IndexListSelected a, td.MailMigrationHighlightedLeftPaneIndex, td.MailMigrationHighlightedLeftPaneContent, .ToolbarItem.ToolbarIcon a.Selected, .LeftNav li.ItemSelected .lnav_itemLnk, .LeftNav li.ItemSelected .lnav_topItem, .LeftNav .t_sel {
color: white;
}

NOTES: The first item is the topbar image. The second item are the selection items. I suggest you use a darker image since this code keeps all text white. I use a nice wood flooring pattern that looks really great.
