Request: Show me all incomplete bundle items

It seems there are two main uses for Gunther's Library - as a reference (recipes, NPC schedules etc), and as a checklist (bundles, perfection, etc).

The checklist functionality is great, but it's a bit fiddly having to go in and out of all the bundles to see what I have and haven't donated. It would be amazing if there was a "todo list" page that just showed everything I haven't donated yet.
