The Translations Behavior screen allows the user to specify which elements of the eSpace should or should not be translated.
However, among the list of elements there is a large amount of elements that are only visible in Service Studio. This is noted on the Location column, however, there is no way to select these elements in order to specify they should not be translated.
Since in 99% of the cases these elements will not be translated (and I really can't figure out what the other 1% of the cases would be, but I leave you the benefit of the doubt), it should be possible to select all these elements easily in order to exclude them. Otherwise we're left with the tedious process of choosing all of them by hand (and there can be thousands of them in a large application), one by one...
Another solution would be simply to exclude these elements from the list. That would be fine by me also.
