Improved testing workflows have accelerated log analysis while the complex interface still needs clarity
There can be improvements in getting error logs more clearly and in a more organized way with AI analysis of what is actually wrong and what can be the solution or how to report that error if it is a bug. That AI analysis can be helpful. Fiddler AI is great to work with, but there can be improvements on the UI. Sometimes Fiddler AI's UI is a bit more complicated because the options sometimes feel confusing when you open the tabs and sub-tabs. This can be an improvement on the UI, and errors can be understood more clearly after an AI analysis of the logs. These are my suggestions for why I did not provide a 10.
