CAUTION : Still WIP. The main functionality works, but it's not a pleasant for the end user for now. Please do test.
The fixed plugin works on Windows. Right now, KDE Connect uses it to establish an initial connection over SFTP, which can then be offloaded to any sftp:// handling application.
Currently, this can be achieved seamlessly by using [WinSCP](https://winscp.net) which is a free and open source SFTP Client.
