I've accepted to release 1.0.5 version of Prettifier to AppCenter but reporting here for your information. The URL https://github.com/fleury08/prettifier/raw/master/data/images/PrettifierJSON.png doesn't work so it won't be actually visible in AppCenter. Rename the file in your repo from PrettifierJson.png to PrettifierJSON.png so that the screenshot can be shown.
