I have very fast FTP connection with big latency. I would like to download/upload multiple files resides in one folder (or selecting them by cmd-a). To speed up whole process it is necessary to transfer files concurrently. Unfortunately to use "concurrent transfer" made already I have to drag and drop all files one by one which is quite painful. I suggest to do something like Number of Concurrent Transfers within one Position in the Transfer window.
