Transition popup's destination should show artboards in Z-order
At present, the list of Destinations within the prototype settings popup (see attached) is shown arbitrarily, seemingly having no sort order at all. For a document with more than a few Artboards, this makes trying to find the one you want really hard.
The expected behaviour from my perspective is that the list of Destinations just follows the existing ordering of Artboards in the Layers panel. This way, a designer can order things as they like and then see the same order shown there.
This is using Adobe XD 18.104.22.168 (latest version at time of writing).
