That’s not very Gneiss of you
Yoohoo! Over here! I did that work. I could do more and (probably) make the “proper “ version of Scratch cope with v3 project files etc.
Err, I advise against that - you’d get the ancient and barely usable version of 1.4. Go for nuscratch instead. But it’s already installed so why would you be doing any of this?
