Putty is used by so many people for SSH connections, I ponder the ability for WinSCP to be able to use the connections already listed inside of Putty to be used by WinSCP. Connections are stored in the registry at

HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\Sessions.

WinSCP would just have parse through the keys to find the proper information. Sure Putty has released PSCP, but it's not as easy as WinSCP is. Theo only reason I suggest this, is that I ssh into servers so much more than move files. And I keep finding servers that I haven't added to WinSCP every once and while. It's just one of those time saver deals.
