Ever wondered what's actually left? The default Achievement UI makes you click through every category to find what you haven't done. Remaining Achievements adds a fourth tab — Remaining — that lists every incomplete achievement on your account in one flat, scrollable, searchable list.

Many of the features below started as community requests and bug reports — thank you, and please keep the feedback coming.

Features

One list, all categories. Native Blizzard achievement rows: icon, points shield, tooltips, click to expand objectives, shift-click to link in chat. Progressive chains show their later steps too, not just the current one.
Search by name or description.
Filter by category. A dropdown of checkboxes (all on by default) lets you hide whole top-level categories — PvP, Pet Battles, whatever you don't chase — from the list, the counts, and the export.
Stash for later. Click the X on a row (or right-click) to set aside an achievement you'll never do. "Show stashed for later (N)" reveals them again with one-click restore. Persists account-wide.
Hidden achievements. A toggle surfaces the point-carrying achievements Blizzard hides from the UI until they're earned — the ones the community calls hidden achievements.
Feats of Strength — obtainable only (beta). A toggle shows the feats you can still actually earn, current season included; retired promotions, old seasonal rewards, realm firsts, and dead one-time events are filtered out.
Opposite faction. Log a character of your other faction and open the tab once — after that, a toggle shows the achievements only that faction can still earn, tagged (Horde)/(Alliance), with combined "(+N Horde)" totals in the header. Built for DataForAzeroth-style completionists who track both sides.
Spreadsheet export. One click builds a table (ID, name, category, points, description, reward, Wowhead link, stashed/hidden/faction flags). Copy it, then paste directly into Google Sheets or Excel — it lands as proper columns, no file or import step needed.
Right-click menu on any row: stash/restore, track on the objectives HUD, link to chat.
Plays nice with ElvUI — the tab picks up your skin.

Usage

Open achievements (Y) and click the Remaining tab. That's it.

Notes

"Remaining" uses the same account-wide completion semantic as the default UI.
The Feats of Strength toggle (beta) is filtered from game data that doesn't track obtainability — if something unobtainable slips through (or something real is missing), please report it and it'll be fixed in the next update.
Retail only; guild achievements are out of scope.
