Autocomplete for Composites
Meanwhile auto-suggestion/completion is there for simple fields (#16 (closed)). Such a feature would be useful vor composite fields as well.
It would roughly work as follows: consider entering an Address in a person form. Instead of 5 individual input fields (Street, Postal Code, ...) just one input field would be shown. When beginning typing (Street, Postal Code, ... whatever) known Addresses would appear in the suggestion menu (just as with simple fields). Choosing from that menu would fill-in all 5 fields automatically. The suggestion menu also features a "New Address ..." special item to be used when the address is not known yet. Choosing this item shows all the 5 input fields then (as in the current Person form).
This is an implementable first sketch. Detail decisions remain.
