From Wikivoyage pub:

One major problem that I found is the lack of green spaces. I would not say that the greenery is absent completely, some parks are displayed of the map, but many of the smaller parks or green spaces like boulevards are missing. This makes the new maps rather dull in appearance and less friendly for users. Will you or Yurik know which features should be added? Another thing is the yellow-orange-colored areas such as parking lots. Those may be also worth adding. --Alexander (talk) 06:12, 22 September 2015 (UTC)
