With LayerSlider WP 3.0.0, you have an option to deep-link a layer. This is means that
you can give a special URL to your users that will open LayerSlider with the desired
layer on start. To do that, you have to add an #ID to your layer and reference in the
URL with a hash or number sign followed this value.
For example if you added the value for the #ID field "surprise", you can reference this
layer with the URL "yourdomain.com/yourpage/#surprise".
