I find my compose font (in plain text mode!) in Ubuntu too small. Can I somewhere in the code change this to a larger size?
Open [RC root]/skins/[skin name]/mail.css and find:
#compose-body
{
min-height: 100px;
height: 100%;
font-size: 9pt;
font-family: "Courier New", Courier, monospace;
}
Change the font-size to to make the text larger.
