Strange, I just opened it there and it works fine for me!
I’ve noticed that with the uiGroups you have to be careful not to accidently move one that’s on top of another because if you do it gets automatically assigned to the lower group again and the whole thing stops working again 🙁
Basically you’re right, probably better off with layers, with that in mind, some questions:
1 When in Layer Editor the Layer listed at the bottom is the only one you can Edit, is that the only consequence of the list order?
2 Does a Layer always cover the entire area of the Panel, with you’re example they seem to?
3 If I used layers then personally I would want certain areas of the Panel to remain unaffected whilst other localised areas changed layers depending on something else, is that possible?
