Display wireframe dimensions and colors for developer handoff
It would be extremely valuable to have a dimension view or developer view where the size and color code for each element is visible. All text or other distractions would be hidden and the user would have the option to reorganize the auto populated layout of dimensions. This feature would definitely put Adobe XD way ahead of any competitor.
There are more variables to consider, but this is an great idea to build off of.
Check out the new Design Specs feature, which released in Beta this week. Your devs will be able to grab dimensions and colors from the link it generates.
