I think it would be helpful to be able to find and highlight multiple sites at once in the map. Say for example I was reading Josh. 7:2-5. There are 5 places mentioned (Shebarim not known to the Site Names tool, at least not in that spelling). It would be helpful to be able to select some verses and amplify to the Map and have all those that could be found highlighted. I realise that the tagging in the texts do not have info on whether something is a place or not. So an alternative might be to augment the Site Names tool with the ability to search by verse reference. You would then still need a way to pass multiple site names to the map during amplify but at least you would have a way to get the list of them.
At the moment I don't see a way to find more than one site in a single operation. If there is a way to do this please let me know.
