Describe the Feature Request In older version of Ionic there was a class TextInput with method focusNext(), which was very helpful in setting focus to next input element.

Using that, we were able to set focus to next input when the user press Enter key.

In Ionic 4, it seems that the class TextInput has been changed and replaced by Input class, which doesn’t have focusNext() method.

It would be great, if this could be added back to the Input class.
