I have a dev version but it is not polished and there's a bug causing 1 object to collapse randomly without warning and that's not great :/
By the way in my real life, I moved to a new flat with new troubles, lost my job, I'm awaiting for a possible new one much further from home and I try tu study Linux to get that job. I also installed Windows 10 and I can't code with it so I will need to install windows 7 just for coding GP4Builder...
Lots of annoyances for a proper release
