Auto-enable fields on click

I just found this project, and immediately added it to my project. Kudos for having both a standalone tool, and making it an easy to integrate library as well!

When building a request, all fields default to unset and you first have to enable them with the checkbox and then can start typing. It'd be neat if you could just click the input field and have that implicitly enable it.

Start by locating the request-building UI where fields have checkboxes and inputs. Verify the behavior around clicking an input, then confirm that clicking it enables the field and allows typing without separately selecting the checkbox.
