I understand that this is not a trivial feature to implement, and that, for me, would be enough to explain why it's not implemented yet. However, my concern is that NNA doesn't understand the importance of this feature and that this may be slowing its development.
I'm willing to concede that I may be wrong but I was just surprised to hear Andrew even ask the question, would it be "that useful?"
As Andrew clearly points out, however, he's only speaking on a personal level so it's unfair to interprete this as a general attitude at NNA.
