There is a feature that we miss from blockly, which is changing the name of a program. In the current version, when you open a program and modifiy it you need to save it with the same name it had. It will be great to be able to save a modified program with a diferent name so we can have different versions of the program. Also, many times, the kids prefer to start a new program by modifying an old one or an example one instead of writing the full program from the beginning. So having to save the (heavily) modifed program with the same name is a problem.
