We have a view in our application that is and photo album. When we have more than 100 pictures in the list, the render is slow. Is it posible to force ember to just render photos which are visible and wait until you do scroll?

We are using [http://runspired.github.io/smoke-and-mirrors/](http://runspired.github.io/smoke-and-mirrors/) to accomplish that. Maybe this addon helps you also 😉
