URL to the section(s) of the book with this problem:
Any code-section with a long first line

Description of the problem:
Symbols such as run, Ferris or that eye-icon overlap with the code on mobile devices. This especially is a problem if the first line is the longest line, thus making it impossible to scoll all of it into view.

Suggested fix:
Add a button bar to the top of each code-section, that contains the necessary items.
