This feature of the day puzzles me somewhat as I would swear this was a feature introduced within the last couple of versions. It is the export of numbers as numbers from a SmartList:
As I mentioned in the introductory paragraph, this is a feature I believe was already introduced, but upon further reflection this may be a slightly different new feature.
The previous feature I am thinking of (but can't find a specific announcement) exported the numbers to five decimal places and without a currency symbol. The example given in the screenshot, above, has a currency symbol and is to two decimal places.
