Changes in JarkViewer 2.0:
 

• Rebuilt tool windows: Settings, printing, editing, batch processing and renaming use Dear ImGui, with DPI scaling, light/dark themes and layouts for smaller windows. Light-theme control outlines, Settings, Help and About have been refreshed.
• Six interface languages: Simplified Chinese, Traditional Chinese, English, Japanese, Korean and Russian, selected manually or from the system. Improved font fallback and Chinese input; fixed duplicate IME text and garbled message boxes.
• Hover thumbnail strip: browse folder thumbnails by clicking, scrolling or using keys, with the current image centered. Built-in decoding provides a fallback when system thumbnail extraction fails; persistent caching and cache clearing are supported.
• Image navigator: a bottom-right overview shows the visible region and supports dragging to reposition. The navigator and thumbnail strip can be toggled in Settings.
• More viewing options: prefer 1:1 display, file sorting, stopping at the last image, a black fullscreen background and reversed WASD panning. Improved zooming around the pointer and panning limits.
• Window and slideshow behavior: titles prioritize the file name alongside its index, dimensions, size and zoom. Monitor and window state are remembered, including negative coordinates on secondary monitors. Slideshows hide navigation, information and other overlays.
