Finding Which Mod an Advancement Came From
Use the click to jump straight to the source
In a kitchen-sink pack it is easy to earn an advancement and have no idea which of the many installed mods it belongs to. The mod solves this by letting you click the advancement name in the chat notification. The Advancement window opens on that exact entry, and the tab it lives under tells you which mod it belongs to. The tab icon and tab name are your answer.
Read the tab and the entry
Once the window is open, look at the selected tab on the left/top of the screen. Each mod contributes its own tab, so the tab you are on identifies the mod. The entry itself shows its title and description, and the lines connecting it to other entries show where it sits in that mod's progression. This lets you see not just the mod, but how far into that mod's advancement tree you have gotten.
Follow the tree for context
From the selected entry you can trace parent advancements backward to see what led here, and children forward to see what comes next. That turns a single confusing notification into a clear picture of your progress in that specific mod, without scrolling through every other tab in the pack.
