SimpleUI (simpleui.koplugin) is a highly customizable, open-source UI plugin for KOReader designed to provide a clean, distraction-free interface that streamlines access to your library and reading statistics.

The principal functionalities of this tool include:

1. Centralized Home Screen

• At-a-Glance Overview: Features a large clock, a "Currently Reading" section with cover art and progress, and a row of up to five recent books for quick resumption.

• Data and Goals: Displays visual progress trackers for annual and daily reading goals, alongside compact stat cards showing reading time, pages read, and streaks.

• Modular Customization: Users can rearrange home screen modules to fit their workflow and resize them independently via per-module scaling.

• Quick Integration: It can be configured as the default startup screen for KOReader.

2. Enhanced Navigation and Status Bars

• Persistent Bottom Bar: Offers up to five customizable tabs for one-tap access to the Library, History, Collections, or system toggles like Wi-Fi and brightness. It includes a "Navpager" mode that replaces standard pagination with touch-friendly arrows.

• Configurable Top Bar: A slim status bar that can display the clock, battery level, Wi-Fi status, RAM, and disk usage, with each item placeable on either the left or right side.

• Reworked Title Bar: Provides a cleaner interface for full-screen views (like the Library) with a dedicated back button, search access, and page numbers.

3. Advanced Library Management

• Folder Covers: Automatically generates custom cover art for folders in the library using the first book found inside, or allows for manual .cover.* image files.

• Quick Actions: Shortcut buttons can be assigned to specific folders, collections, or other KOReader plugins for rapid navigation.

• Bookmark Browser: A dedicated module allows users to browse highlights and bookmarks across their entire library from a single location.

4. Personalization and Localization

• Dynamic Content: Includes an optional "Quote of the Day" module that can pull from a curated list of over 100 quotes or display the user's own highlights.

• Multilingual Support: The plugin automatically detects the UI language from KOReader settings and includes translations for numerous languages, including English, Portuguese, Italian, Polish, Chinese, and French.

• Easy Installation: Distributed as a simple plugin folder that can be dropped into the KOReader directory and configured via the internal "Tools" menu.
