Ethereal Style

Zotero Style, also known as Ethereal Style, is an open-source Zotero plugin that enhances the reference library interface with visual reading indicators and customizable columns. It helps researchers monitor their progress through academic papers and organize collections more effectively. Reading activity can be displayed as color gradients behind document titles. A dedicated progress column visualizes annotation activity across PDF pages. The plugin distinguishes read and unread references through title formatting. It also provides a separate column for tags and additional library organization controls. Its interface enhancements allow researchers to identify unfinished readings and manage large literature collections without opening every document.
