Thanks very much. But it doesn't sound like that would help. First, I doubt a giant network path would fit in the title of a thumbnail.
Second, I want to give focus to the entire application at once. ALL of its windows need to be brought to the foreground at once.
Yes there are limits to how long the title will go until it starts getting truncated so it is possible it won't fit a network path. I'm not sure if the behaviour of the taskbar was always to bring every window of an app to the foreground? But yes I don't think that's a thing either.
