Cursor should remain in input field after adding an item to a Todo list

After adding an item to a Todo list by hitting enter or clicking +, the input field is deselected. When using Android, the keyboard disappears. To add the next item, the input field has to be selected again.
It is actually not a big deal, but it would be easier to add multiple items, e.g. to a shopping list, if the cursor would remain in the input field.
