Mimic "Google Scholar PDF Reader" features

[7vq]

Chrome has a new "Google Scholar PDF Reader" extension for academic articles. The extension allows clicking in-text citations to show, in a popup: the cited article's title, full author list, and article summary. That avoids losing your reading place every time you want to see what paper a citation corresponds to. It also avoids having to manually copy, paste, search, and find each citation online to read the abstract. The extension also automatically adds a linked table of contents for the current PDF, even for PDFs without a built-in linked table of contents.

To convey how much people like these features: the extension was only released a few months ago and already has 100k users.

Could these features be added to pdf.js? (It sounds to me like Firefox wouldn't allow these features to be implemented as a Firefox extension?)

FYI, this Google extension is based on pdf.js
