Thank you so much ! I'm so glad you enjoyed it !
Yes, I'm fixing this issue for the workbench, it will be ready in the upcoming update
For now items can float, I don't know if I'm doing to change it or not, I'm not really bothered by it and I think if it's easier to build like that, why not keeping it ?
I'm not sure what you described here, the panels were linked ? I'm implementing this as I'll add some moving things that need to make tools attached to it move too, but it need polish I imagine
