Visibility based on WP conditional tags

How To
1

WordPress has a pile of conditional tags. Is there a way to use them as an element’s condition w/o adding a custom function?

Example:
I’m building a header template. I want to include 2 versions of the logo. If it’s NOT the home page (front), use the version that’s a link.

I found another approach: custom conditions!

How do you hide the 3 field when creating a custom condition? I’m trying to create a boolean condition. I just need “is true” and “is false”.
