Hey Jeff, before I rate it, I make an improvement suggestion (or else I can’t give 5 stars):
“By default, the plugin includes its JavaScript on every page. To prevent this, and to include its JavaScript only on the chat page, enter the URL where it’s displayed.”
The possibility to limit extra server/browser load is smart foresight, thank you, but for a page URL?
No. Obviously users will want to limit loading to where they actually display the chat. Most will display it in a widget (and if for logged-in users only then obviously in a widget-logic controlled widget for logged-in users only.
Thus I suggest to load its Javascript only on pages where the chat is used (eg in a widget on certain pages). Can you not code it with a hook checking if the chat is displayed on the page? And then loading its Javascript in the footer (at the end).
