New Features

• Lazy loading for page cache: Pages are now cached on-demand instead of all at once when opening a document. This significantly reduces memory usage and speeds up document opening for large PDFs.

• LRU cache eviction: Page cache now uses Least Recently Used (LRU) eviction strategy to automatically free memory when the cache limit is reached.

• Configurable page cache limit: New cache_pages option in [behavior] section to control maximum number of pages cached per document (default: 20).

• Optional cache clearing for inactive tabs: New clear_inactive_cache option to automatically clear page cache when switching away from a tab, further reducing memory usage.

• Cross-window tab drag and drop: Tabs can now be dragged between windows or detached to create new windows.

• Change cursor when selecting or highlighting text

• Searchable text highlights

• Outline widget and Search Highlight widget types - "dialog", "side_panel", "overlay" (configurable in settings)

  • UI
    [ui.outline] - type=<value> where value = dialog, side_panel, overlay
[ui.search_highlight] - type=<value> where value = dialog, side_panel, overlay

• Detection of non-link URL pdf object in the PDF and making them clickable links (optional, configurable in settings)

  • [ui.links]
    • detect_urls - Enable/Disable non-link URL detection and linkification
    • url_regex - Custom regex for URL detection (default is a standard URL regex)

• New options in [behavior]:

  • cache_pages (int): Maximum number of pages to keep cached per document. Default is 20.
  • clear_inactive_cache (bool): Clear page cache when switching away from a tab. Default is false.
