[Plugin] OPDS Plus - Enhanced Catalog Browser with Grid View, Covers & Customization

[visiting5883]

OPDS Plus v1.1.0

Hello everyone,

I have been working on a plugin to enhance the OPDS browsing experience within KOReader. While the built-in browser is functional, I wanted a more visual experience similar to browsing a physical bookshelf or the native store interfaces.

What is OPDS Plus?
This is a standalone plugin that adds a new entry point ("OPDS Plus Catalog") to your file browser menu. It allows you to browse standard OPDS feeds (Project Gutenberg, Standard Ebooks, Calibre-web, Kavita, etc.) with full cover image support.

Features

• View Modes: Switch instantly between List View (with thumbnails) and Grid View.
• Grid Customization:
  • Choose between Compact (4 cols), Balanced (3 cols), or Spacious (2 cols) layouts.
  • Customize grid borders (None, Hash Grid, or Individual Tiles).
• Typography Control:
  • Independent font settings for Titles vs. Author/Info.
  • Adjust font family, size, bolding, and color (High contrast Black or subtle Dark Gray).
• Optimized Performance:
  • Includes a "Debug Mode" toggle for troubleshooting.
  • Smart text truncation for long titles.
  • Efficient image loading (based on the original KOReader logic but enhanced for grids).

Changelog (v1.1.0)

• Added Debug Mode toggle in developer settings.
• Implemented smart text truncation (binary search algorithm) to fit titles perfectly in grid cells.
• Improved grid view sizing to automatically fit maximum rows based on screen height.
• Fixed text measurement calls to use the proper API.
