Maps in Xamarin forms

Hi all,

I have a few questions about maps in forms, all of these things I know how to do in the normal unified way, just wondering how possible they are in maps for forms.

1. Event for location changes, I need this so that I can remove some pins and add new ones based on the location changes.
2. Changing pin images once the pin is on the screen.
3. Put a menu onto a pin touch so I can do certain actions on that specific pin.
4. Drag a pin around on the map.

Basically if I cannot do all of these then I will write this app in the normal non forms way as this will work, but I would love to do this in forms.

thanks

alex
