# Summary
This PR introduces a reusable Tab Bar component and combines the Recent
Books and File Browser into a unified tabbed page called "My Library"
accessible from the Home screen.
## Features
### New Tab Bar Component
A flexible, reusable tab bar component added to `ScreenComponents` that
can be used throughout the application.
### New Scroll Indicator Component
A page position indicator for lists that span multiple pages.
**Features:**
- Up/down arrow indicators
- Current page fraction display (e.g., "1/3")
- Only renders when content spans multiple pages
### My Library Activity
A new unified view combining Recent Books and File Browser into a single
tabbed page.
**Tabs:**
- **Recent** - Shows recently opened books
- **Files** - Browse SD card directory structure
**Navigation:**
- Up/Down or Left/Right: Navigate through list items
- Left/Right (when first item selected): Switch between tabs
- Confirm: Open selected book or enter directory
- Back: Go up directory (Files tab) or return home
- Long press Back: Jump to root directory (Files tab)
**UI Elements:**
- Tab bar with selection indicator
- Scroll/page indicator on right side
- Side button hints (up/down arrows)
- Dynamic bottom button labels ("BACK" in subdirectories, "HOME" at
root)
## Tab Bar Usage
The tab bar component is designed to be reusable across different
activities. Here's how to use it:
### Basic Example
```cpp
#include "ScreenComponents.h"
void MyActivity::render() const {
renderer.clearScreen();
// Define tabs with labels and selection state
std::vector<TabInfo> tabs = {
{"Tab One", currentTab == 0}, // Selected when currentTab is 0
{"Tab Two", currentTab == 1}, // Selected when currentTab is 1
{"Tab Three", currentTab == 2} // Selected when currentTab is 2
};
// Draw tab bar at Y position 15, returns height of the tab bar
int tabBarHeight = ScreenComponents::drawTabBar(renderer, 15, tabs);
// Position your content below the tab bar
int contentStartY = 15 + tabBarHeight + 10; // Add some padding
// Draw content based on selected tab
if (currentTab == 0) {
renderTabOneContent(contentStartY);
} else if (currentTab == 1) {
renderTabTwoContent(contentStartY);
} else {
renderTabThreeContent(contentStartY);
}
renderer.displayBuffer();
}
```

## Summary
Adds support for browsing and downloading books from a Calibre-web
server via OPDS.
How it works
1. Configure server URL in Settings → Calibre Web URL (e.g.,
https://myserver.com:port I use Cloudflare tunnel to make my server
accessible anywhere fwiw)
2. "Calibre Library" will now show on the the home screen
3. Browse the catalog - navigate through categories like "By Newest",
"By Author", "By Series", etc.
4. Download books - select a book and press Confirm to download the EPUB
to your device
Navigation
- Up/Down - Move through entries
- Confirm - Open folder or download book
- Back - Go to parent catalog, or exit to home if at root
- Navigation entries show with > prefix, books show title and author
- Button hints update dynamically ("Open" for folders, "Download" for
books)
Technical details
- Fetches OPDS catalog from {server_url}/opds
- Parses both navigation feeds (catalog links) and acquisition feeds
(downloadable books)
- Maintains navigation history stack for back navigation
- Handles absolute paths in OPDS links correctly (e.g.,
/books/opds/navcatalog/...)
- Downloads EPUBs directly to the SD card root
Note
The server URL should be typed to include https:// if the server
requires it - HTTP→HTTPS redirects may cause SSL errors on ESP32.
## Additional Context
* I also changed the home titles to use uppercase for each word and
added a setting to change the size of the side margins

## Summary
* Swap from Aleo to Bookerly for wider glyph support
* Swap from Space Grotesk to a small Noto Sans
## Additional Context
* 0.11.0 swapped to Aleo which has a few issues (things like Cyrillic
support for eg)
