I'd like to see the transfer queue being remembered from session to session. I script my transfers with WinSCP so that they run overnight, in order to preserve my "peak-time usage" quota enforced by my ISP. I cannot find any way of telling WinSCP to remember the queue so that when I next fire her up, I can see how far through the list the previous execution managed to process.
Failing that, some ability to enable and disable the queue processing at specific times would be incredibly useful. A "scheduler" along the lines found in many BitTorrent clients, available from the GUI would be icing on the cake.
