It would be extremely helpful to view a string list with information regarding the Resource Display availability, such as a column stating "Resource Display" and a Y or N for each string.
In my company, we outsource the translations through bundles. When we receive the translations back from our vendor, the strings have been translated but the UI hasn't been checked. When the string list is long, it is very time-consuming to click on the "Show resource" button for each one (only to realize: "No displays available for this resource type".
This feature is already available by using the Passolo filter function. Resources that can be displayed in the dialog editor have specific resource types and the filter below could be used and adapted so that is then just displays entries of that specific type.
