Description

Description
Allows an extension to insert a button in the blocks toolbox. Once clicked, MakeCode will load a custom editor provided by the extension in an IFrame. The custom editor communicates with MakeCode and is able to provide custom editing experiences.
How to enable it?
Install a package that support editor extensions and a button should appear.
If you cannot see that button and you editor supports this experiment, go to About, then click Experiments and Editor Extensions. If you cannot see this card, your editor does not support yet this feature.
