InvItemMark
by LirxOwO
InvItemMark lets players mark an item in any container so that matching stacks stand out across chests, machines and backpacks.
What it does
A player presses the middle mouse button on an item to create a floating marker. The marker shows the item name and the owner's name, and a container outline highlights the marked item whenever a container with matching items is open. This makes it quicker to locate the same item across several inventories.
Marks work on chests, machines, backpacks and other containers. With FTB Teams installed, marks can be shared with party members, who see each other's marks, while solo players see only their own. Without FTB Teams, players see marks on the server as a whole.
The mod runs on Forge and NeoForge for 1.20.1 and 1.21.1, and is released under the GNU General Public License v3.0 only. The code is open source, and the source code and issue tracker are public. Client and server both need it, since the server has to carry the mod in multiplayer.

Slot highlighting

Use cases
Multiplayer storage
A team that keeps shared chests across a base can mark the items each member needs and find them in any open container.
Machine inputs
A player can mark a resource that feeds a machine and locate it quickly in other storage when the machine runs low.
Who it’s for: Players who manage several containers, and server owners who run teams that share storage. Players who want item markers without a server install should note that the mod needs both sides.
