I find having Capture on when you start Fiddler a pain since almost always one of the first things I have to do is turn it off. I'd like the option to just have it off on startup.
New compression from Google - better than gzip. Supported in Chrome and FF. See site https://www.netwarc.nl/ for an example. Fiddler is unable to decompress the response content.
