This GUI element (which is used by the constant combinator):
is capable of displaying both a number and the quality information of a single signal. Exposing this to the lua API would be great.
Alternative: Add a "quality" attribute to sprite-button (and maybe sprite as well!) to display quality on a regular sprite-button.
support "ChooseLogisticsRequestAndTrashButton" in the lua API
