kdeconnect is near to unusable, at least in the german translation, because most of the plugin-description are totally unclear about which device sends/recieves data/commands/etc… and which device is controlled. Some of the descriptions mentions a mobile which does not help if two computer (desktop/laptop) are connected. The info-windows that are available to every plugin, are no help either, because they do not contain any additional info, only repeat the extremly short description from plugin-list.
