  Features
  
  + Inline Citation Preview
  Hover over any citation and instantly see the full reference. Say goodbye to scrolling to the bottom of the page. Click once to browse the paper's abstract without ever leaving the current page.
  
  + The Navigation Ball
  A compact, beautifully designed controller that replaces the traditional toolbar clutter:
  
  -- Left-click to open the standard toolbar
  -- Double-click to jump to the top of the document
  -- Drag vertically to scroll freely without touching your mouse wheel
  -- Drag horizontally to reveal the table of contents and jump to any section
  
  + Split Window Mode
  Open two views of the same paper side by side for cross-referencing methods with results, or appendix with the text.
  
  + Full Dark Mode
  A true dark mode that inverts and dims the entire page for late-night reading sessions.
  
  + Search With Range
  Limit any search to a specific page range or document section, so you're never wading through irrelevant results.
  
  + Persistent Annotations
  Highlights, underlines, and comments are saved directly into the PDF file. The annotations are fully compatible with other PDF readers and easy to share.
  
  + Direct BibTeX Access
  Copy any citation format, including BibTeX, with a single click from the Cite button.
  
  + Vim Keybindings
  Supports hjkl for scrolling, J/K for page navigation, and gg/G to jump to the top or bottom. More coverage coming soon.
  
  + Fully Customizable
  You can choose a wallpaper (upload or from url) and pick a color scheme for your navigation ball to make it feel like home.

  - One-click copy from any annotated text
