Please add POS item categories with tap-to-filter behaviour, similar to other modern POS systems.

Example use case:

• POS shows top-level categories such as Drinks, Food, Snacks, Desserts

• Tapping Drinks shows only drink items (coffee, juice, soft drinks, etc.)

• Tapping Food shows only food items

• Categories act as a quick filter, not just labels

Benefits:

• Faster checkout during busy periods

• Cleaner, less cluttered POS interface

• Easier staff training (especially for cafés and restaurants)

• Scales well for large menus

This is a standard feature in popular POS systems and would greatly improve usability for businesses using LC App POS as their primary in-store system.
