I'm so glad you created this plugin! This seems like something that should be built into any responsive wordpress theme. Unfortunately, I have not had luck getting it to work for me. No pause/hold on button clicks via smartphone. Here's my site if you care to see it in action: http://www.dzakinsdeli.com/wp

Bottega Theme (Organized Themes)
Tried on iPhone (Chrome/Safari)
Thanks for your help!
