I added buttons to import placemarks from Zh GoogleMap and Zh YandexMap.
I import placemarks from map (Source Map = Google or Yandex) to map (Destination Map = OSM)
In window just start enter map title to select it.
PS autocomplete feature allow you to select map, but if you continue enter letters or remove text, or change map title to incorrect – the “internal id” will not be changed. I will fix it in future – it is not main thing to stop continue development other features, just enter correct data if you wish correct import ;P
