🌟 Key Features: Online Calculator Chrome Extension
	1	Business Ready 🧮 This app is a powerful calculator with memory functionality. It features a full suite of Memory Controls (M+, M-, MR, and MC), advanced decimal logic .00 and .0, and even includes dedicated CASH and CARD buttons for logging payment types, ticket/tape like a point-of-sale receipt.
	2	Persistent State & Complete History 💾 You will never lose your work: the Persistent State automatically saves the current calculation, the full receipt log, and the Memory value (M) even when you close the popup. A dedicated, scrolling receipt log captures every transaction (locally and securly  in your browser) - we don’t record anything online, and you can copy to clipboard and download your log as a .txt file to keep.
	3	Instant Access & High-Contrast Design ✨ Unleash the power of numbers instantly in your browser; a simple click on the Chrome toolbar opens the calculator for effortless, accurate, and efficient calculations. The high-contrast design uses color-coded buttons (e.g., Red for clear functions, Blue for arithmetic, Green for totals) for a sharp, intuitive, and user-friendly experience.
	4	Instantly Recognize 🤓 Clear easy to see ticket tape and a design that resembles the best calculator in finance.
