An honest list, so nothing here is a surprise after you buy.
- No drag into an editor. Not Premiere, not Resolve, not Finder. Files leave only through the download button.
- No PNG export of the board. Removed.
- No drawing. Pen, arrows and rectangles are hidden from the palette. Text notes only.
- The whole board does not play. The ceiling is 16 cards, and by default nothing plays except the card under the cursor.
- No scrubbing on a card. No controls on the board. Sound there is limited on purpose: the hovered card plays with it, every other playing card is muted.
- 720p is what you get, almost always. The download format asks for it first and falls back through looser options, the last of which have no height limit — so a clip offered only above 720p arrives large rather than not at all.
- Moving a card is not undoable. ⌘Z covers notes and drawings only.
- Arrange makes rows, not a grid. Ragged right edge; sizes are never changed.
- Auto-snapshots are not browsable. 60 exist; no interface reaches them.
- The data folder cannot be changed or revealed from the app.
- No sync between machines. The code exists but is switched off in every build.
- No account, sign-up or trial. A licence key, entered once, is the only thing asked of you.
- Not fully offline. Importing needs the network (yt-dlp) and music recognition needs the network (Shazam). Offline, you can browse what you already have.
- No password on a published board. Only an unguessable link.
- One shared link cannot serve two clients. The second overwrites the first's picks.
- Client picks do not come back into the app. You read them in a browser.
- Update failures are never shown.
- Search does not cover captions, URLs or notes. Only title, author, track and artist.
- Windows is not a shipping product (unsigned, no updates).
- There is no About box and no credits screen. The GPL notices themselves are surfaced: Settings → Licences → Third-party notices opens
NOTICES.txt, which ships inside the app and carries the full third-party licence list and the written offer of source required by GPL §3(b).
