Thimble looks like an awesome tool for people who are learning web development (HTML, CSS, Javascript). It's got a simple text editor with previews for both desktop + mobile and lists files. Also includes tutorials Text editor (with dark theme) , preview , list of files and tutorials built in.
The Remix feature is pretty cool too...let's you start with an existing project. Here's an example of the Keep Calm poster project > https://thimble.mozilla.org/anon...
I like the simplicity and elimination of all the noise of a usual text editor which can be confusing and overwhelming for people getting started in coding. I would be interested to seeing what you can do with "Start New Project"
I can see this being really good for new coders. I can't imagine seasoned developers using it but for those learning this is a really good starting point.
