Comment 6 for bug 1732761

The primary bug here, AFAICT, is that multiple values on any given field are not represented in a way similar to the XUL interface, where you could inspect the set of values in use. Here is a branch that provides that functionality:

From the commit message:

Previous to this commit, the display of multiple different values for a field in the item attribute editor was simply to display no value. Here we add a UI component that presents the list of unique values, the number of selected copies that use each value, and the ability to select just those copies using a particular value by clicking on the desired value.
