I would like to suggest the implementation of clipboard integration between Windows Explorer and WinSCP.
In order to keep my sanity, I like to keep the local version of my remote files organised and make extensive use of the synchronize function in WinSCP.
What would be a nice feature is to be able to copy (ctrl-c) a file in Windows Explorer, and then paste (ctrl-v) it into the left window of WinSCP. At the moment, I need to perform a lot of navigation steps in a secondary Windows Explorer in order to move a new file I'm working on into the right folder which will then allow me to upload it using WinSCP. On many, countless actually, occasions I have wished that I could simply switch to the WinSCP window and press ctrl-v. Being able to copy from WinSCP would be nice too, but the paste would be awesome.
The ability to copy from one session (LHS local WinSCP window) and paste into session would also be very useful. This would allow me to move files around more easily when dealing with multiple remote systems.
Cheers and thanks,
