🚀 Version 1.20.26.927 (Latest Release)

📸 3-Stage Hybrid High-Speed HEIC / AVIF Decoder Pipeline

• Step 1: Automatic Detection and Use of Windows Native WIC Codecs

  • When Windows native or extension codecs (HEIF Image Extensions / AV1 Video Extension) are installed on the system, images are loaded at high speed using the OS-level WIC engine.

• Step 2: Portable, Installation-Free libheif x64 Plugin Integration (Fallback 1)

  • Even when system codecs are not installed, the application automatically detects and uses libheif.dll and its dependency libraries (libde265, libdav1d, etc.) when they are available in the application's Plugins\ folder.
  • No static DLL linking (external 'libheif.dll') is used. The decoder uses 100% runtime dynamic binding, so the application remains fully portable and can run as a standalone EXE without any errors or impact when the DLLs are not present.

• Step 3: Friendly Codec Installation Guide Dialog (Fallback 2)

  • If neither Windows WIC codecs nor portable plugins are available, any residual ghosting from the previous image is completely cleared before displaying a helpful codec installation dialog.
  • The dialog provides a direct Microsoft Store link (ms-windows-store://) for the official codec installation, along with a no-install portable plugin guide (https://nztool.blogspot.com/) to make codec installation as easy as possible for users.

🎮 Enhanced Intuitiveness & Hit-Feeling for the Floating Quick Action Control Bar (Pill Toolbar)

• Significantly Enlarged Control Buttons and Icons

  • The floating toolbar buttons have been increased to a more comfortable size (44px wide × 42px high).
  • The Segoe UI Emoji font is used to ensure that icons remain sharp, clear, and highly readable even on high-resolution displays.

• Enhanced Physical Click / Press Feedback

  • When a button is clicked with the mouse, it naturally moves down by 1.5px, creating a subtle physical Push effect.
  • A bright accent highlight and outer rim glow are also applied simultaneously, providing a satisfying, responsive, and tactile clicking experience.

🎬 All-in-One Multi-Media Folder Browsing (Photos + PDF + Novels + Manga + Videos)

• Unified Media Playlist for Mixed Folder Contents
  • Seamlessly browse photos, PDF documents, text novels (.txt), manga archives (.cbz, .zip), and videos (mp4, mkv, avi, wmv, mov, webm, flv, etc.) together in the folder playlist without separating file types.
  • Mini Media Badges on Thumbnail Ribbon: Distinctive color-coded badges (PDF red, TXT mint, CBZ purple, VIDEO blue) on the top-left of thumbnails for instant visual recognition.
  • One-Click / Enter to Read or Play:
    • PDF / TXT / CBZ: Press Enter, double-click the main view, or click the bottom action button ([ 📑 Read PDF (Enter) ], [ 📚 Read Novel (Enter) ], [ 📖 Open Manga (Enter) ]) to enter full dedicated reader mode immediately.
    • Video: Click the central circular play button (▶) or the bottom action button ([ ▶ Play Video (Enter) ]) to play in your system's default media player.
  • Smooth Parent Folder Return (Esc / Backspace):
    • Press Esc or Backspace inside full reader mode to seamlessly return to the exact file index in the parent folder's playlist.
  • Intelligent Archive (ZIP / CBZ) Content Differentiation:
    • If an archive contains no images, it specifically displays "⚠️ No images found in the archive" instead of the generic "Unsupported format or corrupted file".
    • Corrupted archive files are distinctly diagnosed and flagged with "The archive file is corrupted or cannot be opened".
    • Instant toast notifications are also provided when attempting to open or press Enter on non-image archives.
  • Media Filter Preference (Settings F2 ➔ General):

🎨 Full Native Support for Photoshop Large Document Format (PSB)

  • Added 100% native Delphi support for Adobe Photoshop Large Document Format (.psb) files up to 300,000 pixels without any external DLLs or third-party dependencies.

🔒 Password-Protected PDF Detection & Contextual Boundary Navigation

• Intelligent Password-Protected PDF Detection & Dedicated UI

  • Implemented an ultra-lightweight trailer inspection (IsPdfPasswordProtected) to detect encryption within milliseconds.
  • Added a dedicated bottom action button [ 🔒 Open with Default App (Enter) ], enabling users to press Enter or click to immediately launch their default system PDF viewer (Acrobat Reader, Edge, etc.) and enter their credentials.
• Contextual Boundary Navigation Toasts for Documents & Media
  • Eliminated awkward "last folder" toasts when reaching the end of PDF pages or novels:
    • PDF Documents: "This is the last page", "This is the last document" (when no more PDFs exist), and "▶ Next Document: ..." when advancing.
    • Text Novels (.txt): "This is the last page", "This is the last volume", and "▶ Next Volume: ...".
    • Comic Archives (.cbz/.zip): "This is the last chapter/volume", and "▶ Next Chapter: ...".
    • Photo Folders: "Last file reached", and "▶ Next Folder: ...".

⚙️ Configurable Boundary Navigation & Dynamic File Version

• Custom End-of-List Action (Settings F2 ➔ Manga / Navigation)
  • Customize what happens when reaching the first or last item in a folder/archive:
    • Stop (Notify): Toast notification without moving.
    • Loop (Repeat): Wrap around from last to first (or first to last).
    • Prompt (Default): Confirmation modal before moving to the adjacent folder.
    • Auto Advance: Continuously and automatically advance to next/previous chapters.
• Real-Time App File Version in About Screen
  • The About dialog now dynamically queries and displays the actual executable's file version (FileVersion) in real-time instead of hardcoded strings.
