Follow each item’s target
An item is complete when its sacrificed quantity reaches its own research requirement. Mark partial progress rather than treating every item as a single checkbox. Items that share research also share the completion target.
Bring in a character
Open your character file to preview its research, then apply the import explicitly. The file stays on your device. Transferring inventory to the crafting planner is a separate choice; having an item is not the same as researching it.
Find what remains
Filter for unfinished items and follow their database links for recipes and acquisition routes. Progress stays in this browser without signing in. Your collection adds explicit save and load controls for carrying progress between devices.
