Such a useful feature, yet it cannot be used on the server

What do you mean by "yet it cannot be used on server" I believe it can be used on server but you probably meant it can't be used in other inventories, right? There are already mods that do that - Quark or Inventory Profiles Next so I don't feel there's a big need for me to create a mod that would pretty much do the same as they do. If in that changes in the future I may consider it but at the moment you can rely on those mods to get you this functionality in inventories in general.

你说的“但它不能在服务器上使用”是什么意思，我相信它可以在服务器上使用，但你的意思是它不能在其他库存中使用，对吧？已经有 Mod 可以做到这一点 - Quark 或 Inventory Profiles Next，所以我觉得我没有太大的需要创建一个与他们做的几乎相同的 Mod。如果将来发生这种变化，我可能会考虑它，但目前您可以依靠这些 mod 在一般库存中获得此功能。

Sorry, my English isn't very good, and I used a translation software. But Quark and Inventory Profiles Next are too bloated. Most people just want the features for Sort Inventory and Transfer Matching.
