Is it possible to add a feature to the desktop version that asks to add a new customer or suppliers from the create invoice or payment page if the supplier or customer does not exist. This is to avoid having to close the create invoice or payment window whilst adding the customer or supplier.
The desktop version can be accessed through a web browser. Use the “Open in New Tab” option while using the desktop edition to open another instance of the application in your browser and create the new customer or supplier there. Once created, the account will immediately be available for use on the existing page in the desktop app.
