The listing desk
Selling a few. To make room for more, of course.
I may not think I have too many comics, but I do have some I'd like to sell. Selling used to mean an evening of retyping: titles, conditions, prices, photos, once per book, once per auction site.
Now I pick the books in the app and export an auction pack. AirDrop it to the computer, open it, and there's a listing workbench running as a local web page: every book with its photos right there, asking prices to assign, auction houses to choose, honest condition descriptions already drafted from the grading. When I'm done it generates the eBay upload file, and the photo folders are numbered to match, ready to drag into each listing.
Then the part that keeps me honest: the page exports my changes back, and one tap syncs them into inventory. The For Sale tab shows exactly which books are listed where, so a book that's live at auction can't quietly go back in a box and get sold twice. The app even warns me if I try to sell a book somewhere else while a listing is still up. Stay organized!
Behind it: the pack is self-contained and runs offline in any browser. The phone ships raw book facts and photos; the page holds the marketplace know-how. Listings carry states (pending, live, ending) shown as pills on the For Sale view, so nothing listed is ever forgotten.
