Modernises the Portuguese archive sites interface. Among others, it enables a full-screen view of the digitised books and faster page changes.
It is currently not possible to subscribe the extension, as the Chrome Web Store removed access to paid extensions. We are investigating the best way to bring back that possibility.
The annual subscription helps to support the development of this application, and unblocks access to features that are not provided by the archive sites, namely: changing the brightness; changing the contrast; colour inversion; monochrome filter; free rotation (not only 90º like in the free version); etc.
