More trigger methods and multiple select

Hello,

Would it be possible to add some new trigger methods, and make it so we can select multiple instead of just one (checkboxes instead of radio buttons)? Selecting multiple would just use the first selected trigger type that occurs and ignore the rest.

As for other trigger types, I'm thinking:

• On scroll up
• On back button (stop the browser from going back and how modal first)

I've been trying to work on adding some of these things myself but have not been having any luck.
