Presale question: The icon animation effect

Hi there,

I’m interested of purchasing this amazing plugin, however, just have 2 questions regarding the icon animation effect and button action:

1) Like what the demo page shows, would you consider adding a same “flashing effect” to the button, just like what the demo page shows?

2) I would like to open a popup modal on click of the button, which action should I select to realize it?

Thanks very much in advance.
Looking forward to your reply
Regards
