Transaction Entry built-in Calculator

It would be a valuable and convenient enhancement to include a built-in calculator directly within the transaction entry screen - for expenses, income, and transfers. This would allow users to quickly perform calculations—such as splitting bills or adjusting totals—without needing to switch to an external calculator app.

Integrating this feature would streamline data entry, improve user experience, and help ensure more accurate transaction logging, especially in complex or shared expense scenarios.
