After years of suffering with CuteFTP and Filezilla, I will never change again.
So many clever features I can't begin to list them all!
My two complaints:
1. Preferences...confirmations ... overwriting of files.
the checkmark in this checkbox disappears every few weeks. I suddenly notice that files are being overwritten without the chance to confirm and I have to reset the checkbox.
2. When deleting folders in the remote directory, the program asks "Are you sure you want to delete the file 'xyz'? It should ask "Are you sure you want to delete the folder 'xyz'.
