The other problem with removing this feature is that it adds time to the process. The copy and paste does indeed work, sometimes; and the ‘sometimes’ is the problem. Also, the older method immediately put you into the duplicated timeline. The new method does not. You have to copy, then paste and then select the copied timeline. ALSO, the current user manual doesn’t have the new duplicate timeline changes.

Not a well thought out change.
