The URL Display tab of the Options dialog contains the following options to configure how URLs are displayed in the request grid:

Hide https:// prefix for secure requests

Show page relative URLs  

Enabling this option will show requests as a relative path to the URL of the containing page. This will shortened the URLs for assets hosted on the website and highlight resources which are downloaded from other domains.

Display URL Indicators

Select this option to display graphical symbols at the start of the URL to show the type of request (e.g. ➔ for XHR) and a warning triangle (⚠) for requests made with insecure HTTP. See URL Indicators
