guardiangate4110 Since RC 8 JSON doesn't appear to be formatted anymore. In comparison here is the previous behaviour. Version 0.99.126.4.1.8-rc Sonoma (14)
guardiangate4110 Open any JSON file in the browser, like for example http://api.openweathermap.org/data/2.5/weather in the previous release candidate it would automatically format it like in the attached screenshot. I tried toggling Settings -> Advanced -> Rendering: Enable JSON formatting a couple times but it didn't help.
