Type: Feature Request
Improve composer

Fiddler is great but the composer tab really needs some love. For example, it could do with text manipulation features from other applications - double click selects a chunk of text, but it doesn't appear to be aware of common symbols like : ? # " ' ; etc, instead it highlights up to the next space. If i were to do this in vs code or notepad++ it would be more intelligent about delimiters and highlight the portion before the : or inside the " ".


Pressing tab inside the editors moves to the next editor - this seems counter intuitive in this context as you'd expect the editor to insert a tab rather than move you to another field.


I've been using fiddler for years and this has always bugged me. I normally edit the request in another application and paste it in, but it'd be great if i could do some basic editing in fiddler itself. It shouldn't be full ide-mode, but a little bit of help would be appreciated.

Simple things that would make this much better:

  • Add a little syntax highlighting/validation (invalid json for example)
  • Autocomplete for known headers
  • Have the url box be expandable, so you can actually edit long requests
  • Intelligent selection based on delimiters or context
