Some questions before I buy the Fotografie Pro

Hi, I am new with the Fotografie Theme and like it but have 3 Questions: 1. How can I get rid of the Date on the featured content Row? I only like the Headline Link. 2. How can I use a featured image as background of the row at the mainpage, but hide it in the Target Site? Is there another way to set the featured image instead in the post wich contains the Text? 3. Where can I Change "Fotografie by...." in the footer without changing the ThemeCode? Before I buy the Pro Versione I like to know if my 10 wishes are possible with it: A ) more width than ca.756 px wide content without any sidebar, content with left or/and right sidebar for Sites and/or posts. B ) dark theme with customizeable colors C ) one page layout for startpage with prallax effect possible? D ) Extra Entry Site with possibility of HD animated Logo Intro E ) HD background Video for sites possible (from our YouTube Channel)? F ) Video Gallery 3 rows slider (Video with headline by click on the headline above or under a Video opens the video in a new Window with description below the video) G ) full width Site background images chooseable for primary and sub sites prallax or not H ) full width image and or video slider in header I ) google fonts useable J ) social media buttons instagram facebook etc.
