These are features prolific KDP authors, small presses and low-content publishers commonly ask for, each classified with the same honesty as the stated idea. Being in demand doesn't mean you should build it. Demand signals are analyst judgement from forum and tool-market patterns, not a verified survey.

4.2 Demanded features, classified
A. Pricing and royalties (the core, so lean in)
| Feature | Demand signal | Category | Priority | Notes |
|---|
| Bulk price change across selected titles, formats and marketplaces (set, raise by %, round to .99) | High among 20+ title publishers | D | P0 | The core job. Always preview first. |
| "Stuck at 35%" finder: titles priced $2.99–12.99 still on the 35% option | High since July 2026 | D | P0 (free) | The free hook. Read-only, so it's the safest feature too. |
| Bulk royalty-option switch (35% ↔ 70%) with the price rules checked first | High since July 2026 | D | P0 | Validate against KDP's list-price requirements before submitting. |
| Print price-floor check after printing-cost or royalty changes | Medium-high (June 2025 print royalty cut) | D | P1 | Flags books that earn less than expected, or would be rejected. |
| Marketplace price harmoniser (match US price, convert and round per currency) | Medium | D | P1 | Currency rounding per marketplace is tedious by hand. |
| Series price ladder (first book at $0.99 or free, the rest stepped) | Medium | D | P1 | Rapid-release fiction authors do this constantly. |
| Undo and change log (every change, before and after, exportable) | Expected | TS | P0 | Trust. Without undo, nobody lets a tool touch 100 books. |
| Dry-run preview | Expected | TS | P0 | The same. |
| Automatic repricing rules (react to sales rank or competitors) | Loud in seller forums | L | — | Needs scraping Amazon pages and background automation. It's what repricers on Seller Central do through the SP-API, which KDP doesn't offer. |
| Feature | Category | Priority | Notes |
|---|
| Timed promo scheduler (promo price for chosen titles, marketplaces, dates) | D | P1 | The monthly habit that fights churn. |
| Auto-revert on next visit, with a reminder | D | P1 | The user opens KDP, the extension applies the queued change with one click. No background runs. |
| Promo calendar (what's on sale, where, until when) | TS | P1 | Read from your own log, not from Amazon pages. |
| Promo stacking checklist (BookBub, Freebooksy, newsletter dates) | X | P2 | A checklist, not integrations. |
| Fully unattended promo start at midnight | L | — | That's background automation. Offer the reminder instead. |
| Feature | Category | Priority | Notes |
|---|
| Monthly backlist health report (35% titles, price-floor risks, marketplace outliers, missing series links, empty keyword slots) | D | P1 | The reason to open the product when nothing's changing. Emailed monthly. |
| Keyword and category audit (empty slots, duplicates across titles) | D | P2 | Read-only from the user's own Bookshelf. |
| Bulk keyword edit | D / L | P2 | Useful, but it edits content that Amazon reviews. Ship only after pricing is stable. |
| Bulk description (blurb) edit | X | P2 | Rare as a bulk job. |
| Series linking fixer | D | P2 | A frequent support topic for authors. |
| Trademark and content-policy check on titles | L | — | Advice you can't stand behind. Link to Amazon's guidelines instead. |
D. Organisation and workflow
| Feature | Category | Priority | Notes |
|---|
| Filters and saved views (by series, pen name, format, royalty option) | TS | P0 | Needed to pick what to bulk edit. |
| Tags and folders on titles | X | P2 | The Easy Folders pattern. Helpful, but not a reason to pay here. |
| Several KDP accounts or pen names in one licence | D | P1 | The Press plan's reason to exist. Switch accounts the normal way; never store passwords. |
| Team seats (an assistant runs the repricing) | D | P2 | Small presses want it. It's a licence feature, not a login feature. |
| Spreadsheet import and export of price plans | TS | P0 | Presses already live in spreadsheets. |
E. Analytics and research
| Feature | Category | Priority | Notes |
|---|
| Sales and royalties dashboard | X | — | KDP's dashboard, Book Report and Publisher Champ cover it. |
| Profit after ads | X | — | Publisher Champ does it. |
| BSR tracking and competitor research | L / X | — | Scraping Amazon product pages, in a crowded category (Publisher Rocket, KDSpy, Book Bolt). |
| Price-change effect report (sales before and after a change, from the user's own KDP report download) | D | P2 | The only analytics worth doing: it proves the product's value. |
F. Cross-store pricing (the exit valve)
| Feature | Category | Priority | Notes |
|---|
| One promo price across KDP, Kobo Writing Life, Apple Books and Google Play Books | D | P2 (month 9+ gate) | Amazon has no reason to build it. It's also 4× the breakage surface. Build only if ≥30% of payers publish wide. |
| Draft2Digital sync | X | — | D2D already manages the stores it distributes to. |
| Barnes & Noble Press, IngramSpark | X | — | Small share, extra breakage. |
G. Trust and operations
| Feature | Category | Priority | Notes |
|---|
| Human-pace execution (one title at a time, visible, pausable) | TS | P0 | Looks and behaves like the user, because it is the user. |
| Selector health check on load, with anonymous failure reports | TS | P0 | Your breakage alarm. |
| "Not affiliated with Amazon" and "your data stays in your browser" notices | TS | P0 | Chrome Web Store and author trust. |
| Status page for "is it working with KDP today?" | TS | P1 | Cuts support tickets during breakages. |
| Auto-login or stored KDP credentials | L | — | Never. |
4.3 Net effect
Of about 35 features, about 12 are real differentiators for a KDP backlist pricing tool, and about 8 belong in v1 (bulk price, 35% finder, royalty switch, preview, undo, filters, spreadsheet import and export, human-pace execution with a health check). The promo scheduler and the monthly health report follow by day 90, because retention depends on them. Everything that needs background runs, scraping or another platform waits for a gate or never ships.
