It's a great start... I'm sure it'll come along nicely...
I adjusted your theme a bit more today and thought I'd post the info in case anyone else wants to do the same. In the default theme, on the attachment bar of the preview pane there is a clickable arrow which drops down and shows the message headers inline. This is extremely useful for me as I'm still very much in the process of tweaking Spam Assassin, so I located the code in the old theme and merged it into the mail.css.
I realize you can access this info with a right click, and show source - but this quicker... and well, I'm lazy...
Code:
td.show-headers
{
height: 10px;
background: url(images/icons/down_small.gif) no-repeat center;
}
td.hide-headers
{
height: 10px;
background: url(images/icons/up_small.gif) no-repeat center;
}
#all-headers
{
height: 150px;
display: none;
}
#headers-source
{
margin: 0 5px;
padding: 0.5em;
height: 145px;
background: white;
overflow: auto;
font-size: 11px;
white-space: nowrap;
border: 1px solid #999999;
display: none;
text-align: left;
color: #333;
}
Obviously, you have to also copy the gif images the url refers to into the images/icon folders in MobileCube as well. This was inserted at line 1023 in mail.css.
