I added ability use visualization for placemarks.
Now when you create placemark you can set latitude/langitude or/and link to visualization.
If link is done, all properties from placemark will be used for creation visual placemark.
Moreover, you can override popup content and icon by setting its data in structure (added new columns definition).
You can override:
* Addition HTML text
* Date of creation
* Icon Type
If you set that you will use your own data (title or description or addition HTML text) – all predefined data for placemark in this case will be skipped. Ie you can’t mix your data in popup and placemark data in settings.
Documentation will be changed tomorrow.
