I don't know if I am missing this, but I have not found a possibility of having the local files (Folder tab in File Explorer Pane) and the FTP-Files (FTP tab in File Explore Pane) next to each other (or below each other), as is in many other programs so that by clicking a transfer-arrow icon the local file is transferred to the FTP site and vice versa. This (windows next to or below each other) is possible in the *main pane* by selecting 'horzontal split' or 'vertical split' and it would be helpful if this would be possible in the Explorer pane too.
