When entering units, it would be very convenient if one could type the desired unit directly into the input field, instead of relying on a separate selector widget. This is useful for copy&pasting quantities that are already given with a unit ("2m", "7.2kg", etc), and for power users that want to save a few keystrokes/clicks.
There are several options for what "names" would be accepted for unit input:
* The unit's (local resp vocabulary) name (Q-ID)
* The unit's label (localized, with fallback applied). Problem: May not be unique, see {T86528}
* A unique, per language, unit symbol, see {T77983}
* The full URI of the unit
Another open question is the placement of units - are units to be entered after the number(s), or may the be entered before the number, too? Would that depend on the locale, or the unit? Some units are traditionally prepended, especially currency symbols.
