One super easy features to implement, make sure the METHOD box is both user editable and has the defaults like PUT and POST. Another, ability to attach a file to the request when we want to do a PUT to upload an entire file.
Some nice to haves would be maybe a JSON helper to help input fields and data.
Overall, great concept tool. Does what I needed at the time without the hassle of having to know curl command line flags. A weekend of coding and input from the comments could make this an amazing app.
