The word "presets" is misleading. It should be changed to Maps.
This should probably get done sooner than later as the module is still marked as alpha (though that doesn't seem to mean too much in the Drupal community), and this is not a change that should happen once it is in beta. This will include the following:
* Database table name
* Hook changes
* Function change
* Interface wording
Most of the changes are internal and the database changes can be managed with an update function. The hook change will need to include some notification to developers.
