Hello Ed,
Thank you for your question about the snipe button. We have something similar: The Slam-It tool. To install, just drag it from your dashboard (at the lower left) up to your Favorites bar. You may have to enable the Favorites bar. We will have our own on-page snipe button very soon. You can help us test it. :-)
May I ask why you changed from Gixen? Thanks.
