Hi.
I added import placemarks from CSV file (like it is done in Zh GoogleMap), check its documentation (for OSM I hope I’ll write it next month)
https://wiki.zhuk.cc/index.php/Zh_GoogleMap_Description#Import_CSV
I change view for Import from Zh YandexMap and Import from Zh GoogleMap from popups to native joolma style
Fixed a few bugs (undefinite php variables).
Fixed bug from last release for case – placemarks has different groups and enabled clusterization (it were not displayed in some cases)
