Please add a highlighter/marker.

Sahnawaz Alam shared this idea 4 years ago

I really appreciate the efforts kopernio has made for us. I'm grateful that I am using it effectively. I will be highly grateful if there will be a maker or a highlighter. So that we don't have to download it always and read it through some other app.

I think it will be a very useful one.


Hi Sahnawaz,

Thank you for your suggestion.

We don't have immediate plans to implement annotations and highlighting tools for the PDF viewer, but there is an excellent extension that is compatible with Kopernio (and many more PDF viewers), called Hypothesis:

Best wishes,
