Tim is correct above, the arrow should have an option for a move to action, which then you can select to move it up, down or to another zone. If that doesn't work, then you may have to get creative.
What you could try is to use the javascript webparts to load your custom libraries into and then set the enabled property to this macro: {% ViewMode == "LiveSite" %}
This will only load your javascript when you are on the livesite, which should prevent you from having any js issues.
