Robin2:
I may be completely out of my depth here. It seems to me that Blockly is an alternative to the IDE so I don't understand why you would have a plugin.
It can't be an alnternative, it's "over" IDE. So for Kids, I would like them to have some information from IDE in Blockly, to make it very easy to use.
Robin2:
You can use the IDE from the command line to compile and upload a program from any programming language. I use that with Python and I can select the board and port as needed....R
I've done something like that (Blockly@rduino_AIO), but with Java I would like to create something more simple.
