Of course I could copy one by one all fields and settings that the master becomes exactly the same, but isn't there an easier way? In a display there are three options:
- This page(override), the present setting of the display
- All displays
when I use it will mess up my display. For instance in a field it removed all other fields in the display. Not a solution.
- refert to default
which will mess up my display too.
So what is the way to do this besides doing it by hand? May be there is contributed module for this?
