Crahses a lot and has limited functionality
I use this a few times a day, and it will crash fairly frequently on 10.8 (~2x per day).
Its really basic. Whenever I need to do something the least bit complicated, I use a different app. This one I only use to get a JSON tree from GET requests, as otherwise its pretty useless.
Saving a history would be great, as would support for other types of requests, like PUT and DELETE. Setting Header values is also important. Its okay at doing one thing, and one thing only. Could be much better.
