When I was using this project, I encountered three tricky issues

[zhanghengwebs]

Firstly, I added a panel and then deleted it, but I need to display it again. However, when it is displayed again, its position changes. Is there any way to make it return to its original position?
2. When I drag and drop two tab panels within a group, there are no events to listen to their changes, so when I refresh the page, the sub panels will return to their original positions
3. I have a requirement that elements within a specific group (including the current entire group) cannot be dragged into other groups. Can a similar feature be provided

1. Not too sure what you mean here, how are you removing and adding the panel? Do you have a small code snippet?

2. has a current open issue with pending PR Expose event for moving tab within same panel #582

3. should already be posible using the onWillShowOverlay event, I will try and create an example to demonstrate.
