Open and read PDFs in the internal PDF viewer. You can view PDFs in glorious full-screen mode, and the search-as-you-type function allows you to discover all instances of your search term immediately.
You can highlight text with the text marker tool and add sticky notes to capture your thoughts. In the next release (v0.9.6) these annotations can also be synchronized with colleagues, enabling you to share comments on reading material for your research projects.
Now you can manage and view everything in one place: Bibliographic data, PDFs, PDF annotations and highlights, cited references, searchable full-text, keywords, and your tags.
