Flag any unlinked artboard
While all Links are visible (Cmd+A)
Having an error highlight on a Page(s) if it's not linked to another Page.
Example: It would be a nice way to know if you've forgotten to relink Page A to Page C if you've needed to delete Page B.
Unlinked artboard should be marked with defferent color or something. So that user need not to waste time in finding unlinked artboard in review and spec link.
As designers we create numerous art boards. But while prototyping major effort is disappeared. In 1st picture we dont know how many Art boards are being selected. In the 2nd image i could only see only 1/4 screen but as per 1st image all screens are linked.
There could be an option showing "No of Art boards are being linked". So, that we dont have to manually account the Artboard every time to re-confirm in the Prototype link.
Real scenario: 25 art board are linked but could find only 24 art boards in prototype link. It took nearly 1 hr each of 2 designers to figure which screen is not being linked. But all screens are linked properly.
But there was 1 screen which has an Outgoing link but No incoming link.
Suggestion: No. of incoming links & No.of outgoing links would help to show the difference of Unlinked Art board.
