To modify the Message List window, edit the appropriate files as follows:
To customize how the message list appears, edit the listFrameHTML() function in the mbox_fs.html file.
To customize the order in which messages are listed, edit the defaults[] values near the top of the main.js file.
To change the text of default column heading, edit the i18n[] values for search results, date, from, to, size, and subject in the lang/i18n.js file.
To change the text on the “Collect External Mail” button, edit i18n[’collect long] in the lang/i18n.js file.
Functionally, listFrameHTML() calls getSortHeader() in mbox_fs.html and assigns column headings with appropriate call to the sorting function sortMsgs() in main.js. The listFrameHTML() function also links the “Collect External Mail” hyperlink to collect() in main.js.
