We released a new version of IDE today with a couple of improvements:
A “New Model” button to make creating new models easier than ever! Click the “New Model” button, enter a model name, and start writing code (you can also optionally assign one more devices to your new model at the same time!)
Code rollups now persist between sessions (through local storage, i.e. - on the same computer in the same browser). This means that when you rollup some code you don’t want to look at anymore (like the Twitter Class), it will stay rolled up and out of sight.
Here’s the blog post about it with links to the release notes, etc.
