search icon

Hi, I'm still figuring out what to do with this search icon in the navigation bar. I'm very happy with the free version but the only thing that bothers me is this search option. Two questions: 1) Is it possible to change the icon (text or use another 'illustration'=icon)? 2) How to get rid of this icon (and create more space for the menu that way)? Thanks in advance!
