Logo Size in Header and removing social buttons and search field

Hi there, i was using the simple catch free theme, make some customization (i.e. removing the social media buttons and the search field). But I couldn't change the size of the logo which i want to display. I thought if i will buy the pro version of the template I can change it. But after installing I couldn't find the possibility to remove the social media buttons and the search file from the header section. And I cannot optimize the layout, that the logo fits better. Is there somebody how can help me? I activated the free theme again: http://funtasticsix.de Here is the live view of the pro version: http://funtasticsix.de/wp-admin/customize.php?theme=simple-catch-pro (to support you can get account details) regards Frank
