I usually use "Keeping remote directory up to date" function to keep remote directory same as local directory.
We usually need to confirm the file or folder which we changed is really sync to remote directory. But the dialog's synchronization result display area is too small, so I have to drag the vertical and horizontal scroll bars.
So I suggest the "Keeping remote directory up to date ..." dialog should have "Maximize Button" and can adjust size by drag the edge as many softwares do.
Wish WinSCP better and better.
