Missing option in the Forecast Line Details using Enhanced view

Summary:

The new enhancement view forecast version is missing options that we used to find really helpful in the classic view. How do we can now do these things e.g Forecast line details have gone and this was also handy to extend a task date while you were in the middle of forecasting so you could forecast out further.

Can someone advise how to get this Forecast Line Details shows up in the 'Enhanced" view?
