I don't know if this is the proper place to ask these questions but..........

You mention that Python is now incorporated into ARC as the default coding option. I have not used Blocky much so I'm not very knowledgeable on how it works but have used it to help me with coading I was stuck on. I remember that when I put together a script using Blocky I was able to then click on the EZ Script Button in the top left corner and it would translate the blocky diagram into a EZ Script. I don not see a EZ Script button anymore. Now, in the current versio I have of ARC there is only a Javascript button.  This button seems to do the same thing but instead of a EZ Script it will translate it into JavaScript?

With Python support added to ARC and seemingly being your preferred code will there be a Blocky to Python translate button along with a Javascript button?

Anyway to get the Blocky to EZ ScriptTranslation button back?

#2   — Edited

JavaScript will continue being the code that Blockly generates.
