Sioyek 1.5 – Academic PDF Viewer – Now with extension support

Hi! Recently we released sioyek 1.5 with the major new addition of extensions which I am pretty excited about.

See this repository for a sample of what is possible: https://github.com/ahrm/sioyek-python-extensions . For example we have:

* paper_downloader: download papers from google scholar or libgen just by control+clicking on their name (video: https://user-images.githubusercontent.com/6392321/185757545-...)

* extract_highlights: Create a new document from just the highlights of the current documents. We create portals from the new document to the original one so we can quickly jump to the location of highlight in the original document.

* translate: Translate the text and display it in sioyek's statusbar.

I have also created some more experimental extensions which are not yet included in the repository. For example I created a script which indexes all the opened documents using haystack and allows you to do semantic search on your documents. However, currently it is too slow to be really useful.

Anyway, I am really interested in what extensions you think would be useful for a PDF viewer?
