Parallax Frame Pro | customization questions

Hi, thanks for the support so far and I have to admit the Theme and the support I got is awesome. Now that my webpages is filled with content and the starting structure is there, I am ready to evolve ;) I'd like to adjust some minor things to make my http://visualmotion.de website even better: A) on the main page I am using PORTFOLIO and FEATURED CONTENT, how can I include a (lets say white) boarder to visually separate those two in a better way? B) is there a way to automate the FEATURED CONTENT, e.g. automatically using the last 4 posts or the 4 most popular ones? C) I am using the Hero content, but I can't use any formatting options in the content box. However, I am aware that I can use a page instead, but then strangely used pictures got duplicated displayed. How to fix that? Thanks a lot, Michael
