When looking at element attributes or event frame attributes in PI System Explorer I would like to see [string1, string2, string 3] for the value field of an array attribute, instead of "String Array" as we see today.
When you quickly check out the current values of an EF or element, it much easier to recognize the values you're looking for if you see (a preview of) it directly in the Values field for the attribute.
"Hiding" it under the "String Array" key word makes it more difficult to spot!
