Worked well for what i wanted to use it for, simple and useful
Doesn't modify existing http header item.
lacks proper guidance on how to use it.
It works. Perfect tool for testing SSO configurations. The interface is a little weird but it works great. Time saver.
Just couldn't get it to work for me as I wanted & the ux not great :-(
Confusing ugly UI, but it does work. I needed a way to add an Authorization header for a specific URL. For that purpose, this works perfectly.
Modify "Accept" header doesn't work. Settings: "*" "Accept" "application/json,text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8" It also doesn't print to console. Chrome 62.0

Reliable and straightforward. Really needs edit abilities.
URL filter - nice! 5 stars just for that.
