There is a mod called Findme. It allows you to render particles on a chest that contains a relevant item. This got me thinking about how cool it would be if EMI did this when you setup the crafting tree. E.g. you set up the crafting tree bookmarks, it renders particles or highlights the chest containing the items, you open the chest and it highlights the item in the slot. I imagine it would be beneficial in early game and vanilla+ cases where you might have multiple items across many chests that you need to search through in order to locate the resources you want to use.

I can see this being useful. It's a bit against EMI's standard implementation as a client side mod but it's a reasonable ask, so I'll leave it around if this ever becomes more feasible with the design with a performant solution.

There is also a mod called Chest Tracker that tracks your chests on the client-side that already includes EMI support but it's Fabric only. It also only lets you look for one item at a time afaik and not the entire crafting tree at once.
