Wallhaven Enhancer

A high-performance userscript that optimizes the Wallhaven gallery interface with real-time metadata injections, automated hover previews, seamless keyboard browsing, and rate-limit safe background data resolution.

Installation

  1. Install a userscript manager extension such as Tampermonkey, Violentmonkey, or Greasemonkey for your browser.
  2. Click the Install this script button at the top of this Greasy Fork page.
  3. Confirm the installation in your userscript manager dashboard.
  4. Navigate to or refresh any Wallhaven page to activate the enhancer features.

Features

  • Instant Overlay Previews: Hovering over any thumbnail opens an adaptive, high-resolution visual overlay capped at 92vw and 88vh to preserve maximum pixel details without losing visual grid alignment.
  • Lazy-Loaded File Sizes: Displays file size metrics directly on the thumbnail bar. Uses an asynchronous IntersectionObserver coupled with a throttled network queue (50ms sequential cool-down boundary) to pre-fetch header data without triggering Cloudflare rate limits.
  • Intelligent Auto-Close: Previews close instantly when moving the cursor away, triggering manual pointer scroll (wheel), or mobile swipe actions (touchmove).
  • Cached Keyboard Navigation: Preload grid index lists dynamically when the overlay initializes. Prevents redundant DOM queries during fast arrow-key browsing.

Technical Architecture

  • MutationObserver Surveillance Engine: Monitors dynamic DOM append operations (e.g., infinite scrolling). Truncates internal cycles by screening out self-generated modifications originating from the overlay container target block (#whOv).
  • Decoupled Concurrency Loop: Offloads extension sorting and payload delivery to a prioritized data queue (networkQueue), restricting execution matrices to a rigid, deterministic sequence.
  • Memory Optimization: Leverages a local localStorage eviction mechanism limited strictly to the top 2000 entries to prevent localized overhead creep. Automatically recycles unused memory blocks using URL.revokeObjectURL handlers during manual browser download streams.
