Integrating Droplet into Applab ? Improving the usability of a blocks-based text editor

Droplet is a programming editor that allows dual-mode editing in blocks and text for any text program. This paper presents observations and improvements to Droplet based on integrating Droplet into Applab, Code.org´s JavaScript sandbox learning environment. Droplet´s unique interactions with both text and blocks create several unusual problems and opportunities for improvement.
