Remaining Achievements — a "Remaining" tab that lists every achievement you haven't done yet (feedback wanted)

I got tired of clicking through every achievement category to figure out what I actually had left, so I built an addon that does it for me — and it's now up on CurseForge. Sharing it here because a lot of the current features came straight from community bug reports and requests, and I'd love more eyes on it.

What it does: adds a fourth tab — Remaining — to the default Achievement UI (open with Y). It lists every incomplete achievement on your account in one flat, searchable, scrollable list. No more spelunking through categories.

Features:

- One list, all categories — native Blizzard rows: icons, point shields, 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 — checkboxes to hide whole top-level categories (PvP, Pet Battles, whatever you don't chase) from the list, counts, and export.

- Stash for later — set aside achievements you'll never do; toggle them back with one-click restore. Persists account-wide.

- Hidden achievements — a toggle surfaces the point-carrying achievements Blizzard hides from the UI until earned.

- Feats of Strength (obtainable only) (beta) — shows the feats you can still actually earn, current season included; retired promotions, old seasonal rewards, realm firsts, and dead one-time events filtered out.

- Opposite faction — log a character of your other faction, open the tab once, and after that a toggle shows the achievements only that faction can earn, tagged (Horde)/(Alliance) with combined totals in the header. Built for DataForAzeroth-style both-sides completionists.

- Spreadsheet export — one click builds a table (ID, name, category, points, description, reward, Wowhead link, flags) you can paste straight into Google Sheets or Excel as proper columns.

- 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.

Retail only; guild achievements are out of scope.

Feedback I'm especially after:

- The Feats of Strength filter is the one heuristic-based feature and still in beta — the game data doesn't actually track obtainability, so I derive it. If you see a feat that's unobtainable slip through, or a real one that's missing, please tell me (a screenshot or the achievement name/ID is perfect).

- Anything that feels off on the opposite-faction view.

- General "I wish it also did X."

Thanks for taking a look — happy to answer questions in the comments.
