Greetings!
It’s probably been noticed, but the page is hard coded to only display 50 items. So you can’t view, purchase or download individual clips from the packs that contain for than 50 elements? It should be simple enough to change the CSS to allow a scrolling window based on the number of elements.
This includes basically all the crowd packs, electrical sparks, grinding sparks, some of the larger fire packs, etc.
Hard to sell visual elements that can’t be seen 
Sight looks good though!
