Thank for the feedback and for using Fiddler Everywhere!
I can confirm that we have identified this issue, and the team is already working on improving the Fiddler Everywhere app and dashboard site capabilities. One of the changes that are about to come is a functionality that will allow changing the screen name. Stay tuned for updates - I will update this thread as soon as these changes are live!
I am using a free account, but at the time I signed up I made a typo in my name. Is there any place where I can update my name?
Not big deal, but just annoying not to be able to update your profile.
