While probably somewhat of a paint to write the UI for, it’d be great if it could just ask me. The import box would have a “automatically found [X/Y]” as it does now, but a new “[Z] uncertain items remaining” section at the bottom, then if any issue items the “Add X items” button becomes a “Resolve Next Item”. Click it you are shown the first issue, pick right pinyin/definition, hit next item and keep going until everything is resolved then you get the existing “Add X items” button to finalise the list. So it just takes you through the problem items and lets you pick a resolution.
Being able to find the item and add it manually back in is fine - but is there any way to re-order the list? I tried to re-add my issue items but they all went to the end. Which is not terrible, but being able to put them back into their correct order would also be fine fallback.
Yeah I agree do that! It’s exactly what I want so it’s clearly a great idea 
Yep - definitely have both. Start with public lists so community can build out a whole backlog of it without responsibility falling to you guys, but then just publish your own as you feel like it (and then just have some neat branding on any official list published by the “HH Team”!
