Teleporter brings smooth SPA-like (Single Page Application) transitions to your WordPress site. External links work as normal, but new pages on the same site are faded in magically when they are loaded and pages that have already been visited are instantly faded back in without needing to reload.
Teleporter uses fullpage iframe swapping, rather than AJAX. So unlike AJAX Page Loaders, this means that all the javascript in any pages loaded will continue to run as it normally would, giving visitors a seamless experience while navigating your site.

Teleporter

Great idea. Overall, it seems to work well. There is a PHP warning you should check out about "count()."

One other suggestion: There needs to be a way to make the plugin ignore certain links. For example, at my website clicking reply in the comments doesn't work on the first click because this plugin thinks it needs to do something. Besides that, maybe someone just wants a certain internal link to cause a full/regular page reload.

I love the effect though. :)

Great idea

Seamless fading page loading transitions via the Browser History API.
