That would be definitely a plugin. It would do an ajax request just
after initial getunread request, where it would go through list of
folders doing an imap search for "unread messages arrived in last 24 hours".

Some hints for PHP code:

$rcmail    = rcmail::get_instance();
$storage   = $rcmail->get_storage();
$a_folders = $storage->list_folders_subscribed('', '*', 'mail');
$unseen_folders = array();

foreach ($a_folders as $mbox) {
    // IMAP SEARCH supports date-only format
    $index = $storage->search_once($mbox, 'UNSEEN SINCE ...');
    if ($index->count()) {
        $unseen_folders[] = $mbox;
    // you may also/instead need to check timestamp of the most recent

$rcmail->output->command('set_unseen_folders', $unseen_folders);

Of course, you'd need the client-side part that does the request and
updates folders classes.

Also, considering performance you might need to store the list of unseen
folders in some database and update the state when you like and remember
when the user visited such a folder to not mark it unseen again, etc.
