Lots of Modpack are bundling both Quark and ActuallyAdditions in. While people don't have a full blown ME system, they rely more heavily on the Small Crate from Actually Additions to store all their goods. Being integrated with Crafting Station means you can go a long ways only needing to upgrade to a medium crate.
The problem is that the Crate UI is so large oft-times I find I'm staring at the inventory hunting down the item I'm looking for. JEI allows you to search for an item and hover your mouse over an item and press 't' resulting in chests with that item 'smoking', but if those inventories are crates it is a pain finding the right item inside.
That is where Quark would be really helpful. Your search bar at the bottom of vanilla chests is really helpful, but would be even more awesome if it was ported to these crates. One big complication is that medium crates have an arrow to get to the next page of items. If your search bar was ported we'd need to switch pages for the user if no matches are found on the current page but are on another page. The Large Crate gives 4 pages to look at. Needing to navigate these 4 pages really turns me off from this option, but your search bar would fix that problem.

i realize that your mod is meant to be independent from these other mods. So if you can't special-case the Actually Additions crate in this mod, then please consider offering a PR to their github repo to add your code to their inventory.
