Dev Mode: focused node in Plugin API
Plugins running in Figma Dev Mode can now read the node currently focused in the Dev Mode focus view. The existing figma.currentPage.focusedNode property (already used in Figma Slides and Figma Buzz for the focused slide or asset) now returns that node in Dev Mode as well. See Working in Dev Mode for more on building plugins for Dev Mode.
