Pre purchase questions

Hi, I have a couple of questions about the plugin and what is possible. It would be useful to know if the functionality is available either with the Free or the Advanced plugin.

1) I can see that there is an ability to add multiple marker categories in the free plugin, and I have seen (in the demo) that there is a capability in the advanced plugin to be able to switch these layers on and off. Is that functionality only available in the advanced plugin?

2) I would like the ability to have just a single specified marker shown on page load with all of the other options available to turn on via their category layers. Is this possible?

3) I would like the ability to be able to turn off the featureType POI within the map. I can do it by editing the JS code directly but is there a way to do it within the plugin?

Thanks, Daz
