Has anyone experienced "Export Failed: The file is corrupted and cannot be opened" when exporting .note files to PDF via the Partner app on Mac?

I'm on a Manta (A5 X2), latest firmware. Files sync fine via Supernote Cloud and display correctly in the Partner app (EXPORT > Manta), but every file fails when I try to export as PDF. All four files I've tested produce the same error — sizes range from 570 KB to 1.4 MB.

I also tried supernote-tool (supernotelib 0.7.0) as a workaround for batch conversion, but it throws UnsupportedFileFormat — the .note format version is 20260016, which the library doesn't recognize yet.

Anyone else hitting this with recent firmware? Open to workarounds — especially anything that supports bulk .note → PDF conversion without doing it one-by-one on the device.

Plug-in support needed

Hey, building a third-party plugin. Can anyone confirm whether expandMenuItem: 1 in registerButton() actually places a plugin button directly in the main toolbar (not the plugin submenu) on current Chauvet firmware? Testing on Manta 3.27.42 beta and it still appears in the submenu. Any workarounds known?

Mulan Skill for Claude

Here you go:

Mulan — Supernote AI Skill for Claude

A free custom skill for Claude (download on Github) that acts as a knowledgeable Supernote specialist. Instead of generic e-ink answers, you get responses grounded in real device knowledge and community experience from r/Supernote.

What Mulan knows

  • All Supernote devices — Manta, Nomad, A5 X, A6 X — including how they differ
  • Full pen and folio ecosystem with device-specific recommendations
  • Chauvet OS, firmware versions, stable vs. beta, what landed when
  • Workflows — journaling, reading/annotation, meeting notes, research, sketching, PKM integration
  • Templates and InkHub — finding them, importing them, PDF vs. native tradeoffs
  • GitHub tools — supernote-tool, Obsidian plugin, sideloading, .note conversion
  • Troubleshooting — battery, sync, OCR, FeelWrite break-in, WebDAV, sideloading errors
  • Honest buyer's guide mode — including when a Supernote is the wrong device
  • Community wisdom from r/Supernote — the stuff that only comes from actually using one

Keeping Mulan current

Type "update Mulan skill" at any time and she'll search the official Supernote changelog, r/Supernote, and GitHub for what's changed — then show you exactly what she wants to update before touching anything.

Requirements

  • Claude.ai Pro account (skills feature requires Pro)
  • The mulan-community.skill file from this repo

Setup

Download SETUP.md for the full walkthrough. The short version: install the skill file in Claude, open it in a text editor, fill in the YOUR SETUP block with your device and workflow, re-upload. Five minutes.

Supernote please address the inconsistency of the lasso gesture. It's a real friction point when in flow state. Side note, I created a Supernote skill for Claude named "Mulan". Its grounded in the manual, Reddit, and plug-in architecture/dev. Mulan's skill extends beyond Reddit!!
