# POS UI Optimization

This Odoo 17 module optimizes the Point of Sale (POS) user interface for low-RAM devices (e.g., Android tablets with 2GB RAM).

## Features

- **Product List Incremental Loading**: Renders products in batches of 40 as you scroll, significantly reducing memory usage in categories with many products.
- **Order Cart Incremental Loading**: Efficiently handles large orders by rendering order lines incrementally as you scroll through the cart.
- **Improved Responsiveness**: Keeps the browser DOM light and prevents "white blank" screens caused by memory exhaustion.

## Installation

1. Place the `pos_ui_optimization` folder in your Odoo custom addons directory.
2. Restart your Odoo server.
3. In Odoo, activate **Developer Mode**.
4. Go to **Apps** -> **Update Apps List**.
5. Search for `POS UI Optimization`.
6. Click **Install**.

## Technical Details

This module uses Odoo's JavaScript patching mechanism (`patch` from `@web/core/utils/patch`) to extend the core POS components:
- `ProductsWidget`: Adds `displayedCount` state and a scroll listener to the product container.
- `OrderWidget`: Adds `displayedCount` state and a scroll listener to the order container.

No core Odoo files are modified.
