Zotero Style is a plugin for the Zotero reference manager that adds a set of interface enhancements for organizing and exploring research libraries. It provides tools for customizing PDF appearance, adding configurable tag columns with hierarchical nesting, saving and switching between multiple column layout views, tracking reading progress, and visualizing item relationships in an interactive graph.
The plugin distinguishes itself through several specific capabilities: a relation graph that displays connected items and supports click-to-locate and focus-node interactions; a reading progress tracker that represents per-page reading time as a background color gradient on the title column, alongside annotation word counts; a tag column configurator that parses tag prefixes into nested hierarchies and automatically ranks tags; and a view layout manager that preserves multiple column visibility configurations as named presets. Additional per-item controls include star ratings and read/unread status markers shown in dedicated columns.
Beyond these core additions, the plugin integrates PDF style customization through a long-press menu and palette button, and supports item type filtering triggered from the type icon. It stores user preferences such as column layouts and ratings locally via a JSON file kept in Zotero’s data directory.
The plugin installs through Zotero’s add-on system and hooks into the item pane and PDF viewer via official extension APIs.
