I'd second this request. Would be very handy to have a clear indicator as to if an image had been successfully transmitted, maybe even a traffic light sequence, red queued, amber sending, green sent or something similar.
Also, in the FTP, at least on my Mac, I find I cannot cancel a current transmit without cancelling the whole queue. The stop box is simply not highlighted. Almost every event I cover, if it's on a slow connection, I give up using PM and use Transmit to send the files as PM keeps locking the queue and doesn't recover. Are there any plans to expand and refine the FTP element of PM?
