Product and version: 16.02
OS and version: Mac El Capitan
Before 16, I would often select a group of fields or their labels, then look at Position Inspector to see if they are all the same height or width. (I want them the same for precision, good-looking layouts. Minor differences are easily seen by the human eye.)
In 15, if the individual heights and widths are the same, their common, individual width or height displays. If not the same, those Inspector fields would display a hyphen. Because the Inspector now gives only the total, I have to click on each object individually to see its height.
Workaround Click each object individually.
Comment: I'm sure many users would desire the total height and width. How to show if they are all the same? Maybe something like an option-click?
