## Review summary

Users praise the add-on as a reliable, cross‑platform ZIM reader that provides fast offline access and privacy benefits. Repeated complaints are that it only accepts .zim files (no EPUB/PDF/book options) and lacks convenient multi‑archive opening or library management. Overall it works well for its core purpose but needs better format support and archive management.

### Pros

- Reliable ZIM archive reader — consistently opens ZIM files from local drives and removable media.
- Enables fast, offline access to Wikipedia/Wiktionary; useful for users with limited or no internet and for privacy-minded use.
- Cross-platform and portable — works across operating systems and from SD cards/USB drives, making it handy on multiple machines.

### Cons

- Only supports the .zim format; users want import/export or article-book options like EPUB/PDF.
- No easy way to open, switch between, or manage multiple ZIM archives within the add‑on (multi‑archive/library features are missing).
