Enhance the user interface of Portuguese digital archive document viewers

The native archive viewer interfaces are often difficult to use for reading digitized books/documents. This extension provides a modern, full-screen overlay with better navigation and image adjustment controls.

1. User navigates to a supported Portuguese archive viewer URL (e.g., digitarq.arquivos.pt/fileViewer or various archive sites). 2. The extension automatically injects an overlay UI on top of the archive viewer. 3. User can navigate pages, zoom, rotate, adjust brightness/contrast, invert colors, print, or download images. 4. A backlink to tombo.pt is provided for reference.

Target users: Researchers, students, and general public accessing Portuguese digital archives (e.g., arquivos.pt, adb.uminho.pt, various municipal archives) / Users who need to read digitized books/documents with better visual controls

The extension code is heavily minified, making some logic harder to trace. However, the key behaviors (UI overlay, no login, no payment) are clear from the manifest, overlay.html, and message files.
The extension communicates with tombo.pt for reference links but does not appear to send user data or require authentication with tombo.pt.
The extension supports many different archive domains, but we only analyzed the common patterns; edge cases on specific archive sites may have unique behaviors.

Monetization

No paid features detected

The extension is free with no paid features, subscriptions, or billing logic. The 'pro' and 'license' keyword matches in the static analysis are false positives: 'pro' appears in minified code unrelated to paid plans, and 'license' references are standard MIT license headers for third-party libraries (jquery.panzoom, printJS). There are no payment platforms, upgrade prompts, or feature-gating mechanisms.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension is a client-side UI overlay for viewing digitized documents on Portuguese archive sites. It does not implement any login mechanism, nor does it redirect to a login page. The core workflow (viewing, zooming, rotating, adjusting contrast/brightness of images) works directly on the archive viewer pages without requiring user authentication.
