@nkh Maybe we can give the user a switching option to decide for themselves?

@qindapao. it makes no sense to disconnect objects moves as a group.

if the user wants to disconnect, she can disconnect the object first then move, or move and then disconnect.

@nkh It seems that the connector enable or disable for the box is only in the right-click menu. I think it can be made into a shortcut key.

I don't want to use the right-click menu anymore since we have the current shortcut keys haha.

@nkh Of course, I'm not saying that right-click menus are not good, they are also part of the software.
