Template SMOOTH SCROLL TITLE: showdate and source

Hallo,
I use you useful plugin for my site with ‘SMOOTH SCROLL TITLE’ template (I encountered a few problem with the other ones).

You find an example here: https://www.gallinagiacinto.it/portfolio/eventi-asti-e-dintorni/

As you can see, I personalized the style through CSS.

My questions are:
1) since some feeds have not their own image, can I force a default one?
2) I’d like to set a maximum lenght for title: is there a way (shortcode?)?
3) I’d like to make date and source appear under the image, but the shortcode I use for date ([…showdate=”1″]) was not good. No shortcode for the source of the feed.
4) No way to make the warning of the ‘Start here page’ disappear, even following instructions and updating database.
5) No way to go to the page to customize template through the link ‘…/options-general.php?page=wp_rss_multi_importer_admin&tab=template_options’ you gave in the Shortcode Settings: the answer is ‘You do not have sufficient permissions to access this page’, even if I am admin of my site.

Thank you very much for you plugin:-)

Bye

Pier

P.S.: here is the implementation to CSS:

#wprssmi_RssParade {
    height: 290px !important;
}

#wprssmi_RssParade div.scrollableArea .wprssmi_item_inner {
    background: none repeat scroll 0 0 rgba(255, 255, 255, 0.1) !important;
    border: none !important;
    border-radius: 0 10px 10px 0 !important;
    box-shadow: 10px 2px 10px 0 rgba(50, 0, 50, 0.75) !important;
    margin-right: 20px !important;
    margin-top: 20px !important;
}

div#wprssmi_main_container {
    font-size: 9px !important;
    text-align: left !important;
    width: 620px !important;
}

div.wprssmi_container {
    padding: 6px !important;
}

div.wprssmi-excerpt {
    font-size: 10px !important;
}

div.wprssmi_item_inner {
    font-weight: bold !important;
    height: 250px !important;
    width: 175px !important;
}

p.wprssmi_title {
    height: 70px !important;
}

a.colorbox.cboxElement {
    color: maroon !important;
    font-size: 75% !important;
    padding-right: 20px !important;
}

.imagefix img {
    border: 1px solid #fff !important;
    border-radius: 10px !important;
    height: 90px !important;
    max-width: 150px !important;
    max-height: 90px !important;
    width: 150px !important;
}
