Lazy Load + Unload Option

Continuing the thread from #1168

I have a use-case where each slide item is pretty complex and i have potentially 100s of items. I currently use lazy-load which is great for the first few items, but then gets exponentially worse as I add more and more items. If there was a way to unload the items after you've viewed them (ie. after swiping left to go to the next image) that could significantly help the runtime of my use case. Is there any chance you guys could develop something like this?
