Add a large, easily accessible quick payment button on the main screen of the wallet. Clicking button should open QR scanner to scan details of a single payment - currency, amounts, memo or title and all other data encoded in QR code. After scanning the wallet would display transaction confirmation screen. User should be allowed to edit such payment details only after confirmation he/she wants to do so. Otherwise editing should be disabled.
Thank you for your suggestion. We are considering design changes on main screen by adding send and receive buttons and now working on providing you best user experience.
