Wrong focus behavior memo items

[Renato Araujo Oliveira Filho]

1 - On the Details view: when press the "Add Item" button the cursor should be focused in the new field that gets added and this should be scrolled into view above the keyboard.

2 - if editing a item and press the "Next" key on the keyboard It should move to the next item in the list and make sure that is scrolled into view

3 - After typing in the new item and pressing "Add" from the keyboard the focus should move to the next field and that field should be visibile, currently the top of the list is displayed but the keyboard remains open.
