I have (also) needed to copy and paste certain fields from this area many, MANY times, but for some reason, I thought it was just me who wasn't able to, because maybe my computer had a bug or something with the software that didn't allow this to work. Anyway, looking back on it, I have no clue why I had this weird belief, but still, now I know that it wasn't just me who couldn't copy and paste; it has never been a feature at all... :-P
Nevertheless, my point is that several other people want this feature, also, so please implement this sooner than later... Thanks, mistercz!
