Maybe one day.

For now I'm just going to sit here and ingest my screen resolution envy. 😛

I've made these quick and dirty changes:

/* occupy more space */
body.index-page #sub_nav,
body.index-page #content,
body.index-page div#header-constrain {
	max-width: 95%;
}

/* search input behaves strange when wide, don't have time to deal with this - just move it down */
body.index-page #basic_search {
	height: 35px;
}

/* fix squished logo during login */
#login-title #header-image img {
	height: 100%;
}

Seems to work, for now. Now to find the line of code that trims the subject line...

So turns out the subject is trimmed with css and not code:

/* full width subjects */
body.index-page .osta_subject > span.truncate {
	max-width: 100% !important;
}
