//consider: with the preload, may want to notify user bg loading is happening, but not block them from seeing the products.
// - loader bar across the top of the filters? ajax finish ++ / total ajax? guestimate total ajax/4 ajax at a time*3secs per ajax?
// - simple text note "More products are being filtered" ?
// - nothing: Although the filter system offers a lot of non-shopify options, nearly everything used to date is still within S's native collections or collections/tag
// this means the preload page is going to be the actual page.
//TODO: needs grid css to put the filters on the left. Might also want to hide/show filter block.
// - maybe: use a drawer to hold filters. On mobile, would let you flip back and
// forth. on desktop, would let you scroll both independently.
//TODO: mobile filter, either the drawer or the MWK style
//TODO: COMPARISON SHOP concept
//TODO: ARIA on the product grid
//Consider: misook's test showed an increase in sales with the filter horizontal.
// - might also make it mobile friendlier
