How should I track requests for very small changes in the user interface of my Agile project?
These changes will take very little time to complete and require only a few words to specify. However, they have originated with the customer, and it is therefore very important that they are not overlooked. Creating a 'User Story' seems too heavy handed for very small and isolated changes like this. A 'Task' doesn't seem right as the origin is not internal. A 'Bug' would imply unintentional behaviour to be corrected.
Example request: "In the membership status screen, please change the word 'Resigned' to 'Cancelled'".
