There are some things you could tweak in this module that are not (yet) available in the module settings.

Arrows

There are several different arrows included in the Portfolio Catalog module.

The default arrows are and , but in the directory /modules/portfolio/images/ you will find some more arrows you could use.

- - - and more..

The view.php file has all settings for these arrow sets preset.
 

$left = 'arrow-l.gif'; $right = 'arrow-r.gif'; $arrowheight = 32; $arrowwidth = 32;
//$left = 'arrowLeft.gif'; $right = 'arrowRight.gif'; $arrowheight = 38; $arrowwidth = 40;
//$left = 'leftnav.gif'; $right = 'rightnav.gif'; $arrowheight = 24; $arrowwidth = 24;
//$left = 'fat_arrow_left.gif'; $right = 'fat_arrow_right.gif'; $arrowheight = 50; $arrowwidth = 50;
//$left = 'sbArrow_left.gif'; $right = 'sbArrow_right.gif'; $arrowheight = 47; $arrowwidth = 46;
//$left = 'arrow-left.jpg'; $right = 'arrow-right.jpg'; $arrowheight = 44; $arrowwidth = 44;

Just edit the view.php page with a tool like the Addon File Editor, uncomment the line with the arrows you like to use and save the page.

Carousel width

If you use the calculation of the carousel width correctly, the last image in the carousel will shift to the left leaving an empty placeholder (where the next image would be).
I found that adding one pixel to the width will make the carousel not to show this empty placeholder.

User Defined Fields

Note that you can use the User Defined Fields also in the WYSIWYG part.
It might be handy if you use some standard text or table setup to add variables to the page and use them in the WYSIWYG part.

Droplets

Droplets can be used in the fields (not the field names) and in the template wherever you like.
