## Features

- Smooth zoom animations with visual feedback
- Pan around slides when zoomed in by dragging
- Customizable zoom range, steps, and pan boundaries
- Simple popup settings interface
- Configurable limits:
- Zoom range: adjustable (default 100% to 300%)
- Keyboard zoom step: adjustable (default 10%)
- Scroll zoom step: adjustable (default 20%)
- Pan boundary: adjustable (default 50% of slide)
## Installation
1. Navigate to `chrome://extensions/` in Chrome
2. Enable "Developer mode"
3. Click "Load unpacked" and select this folder
4. The extension will activate on Google Slides presentations
## Usage
### Controls
| Function | Shortcut / Gesture |
| --- | --- |
| Zoom in | `Ctrl/Cmd` + `+` or `=` |
| Zoom out | `Ctrl/Cmd` + `-` |
| Smooth zoom | `Ctrl/Cmd` + mouse scroll / touchpad pinch |
| Reset zoom | `Ctrl/Cmd` + `0` or `R`
or Double-click (when zoomed) |
| Pan (drag view) | Click and drag (when zoomed) |
### Settings
Click the extension icon to open the settings popup where you can configure:
- **Min Scale**: Minimum zoom level (default: 1.0 = 100%)
- **Max Scale**: Maximum zoom level (default: 3.0 = 300%)
- **Key Step**: Zoom increment for keyboard shortcuts (default: 0.1 = 10%)
- **Scroll Step**: Zoom increment for mouse scroll (default: 0.2 = 20%)
- **Pan Boundary**: How far you can drag the slide off-screen
- `0` = Can only pan to see content edges (no overflow)
- `0.5` = Can pan half the slide off-screen (default)
- `1.0` = Can pan entire slide off-screen
After changing settings, refresh your Google Slides presentation to apply changes.
## Technical Details
- Applies CSS `transform: scale()` to `.sketchyViewerContent` with smooth transitions
- Settings stored in `chrome.storage.sync` for persistence across devices
- Pan limits dynamically calculated based on viewport size and zoom level
- Drag-to-pan overlay prevents interaction with slide elements when zoomed
