Cannot Stop Downloading Proccess

There is no stop button in the downloading window and again if the X button on the top-right corner of the window is pressed nothing happens.

Cannot Stop Downloading or Uploading #5
Thanks for making this SFTP client. As [rahulsdhar] (https://github.com/rahulsdhar) has already written about the issue, I'm also having the same problem. If you add these two options (Upload/Download Stop Buttons), It would be appreciated.
Thanks.
