Undo command does not work after exiting application

[mgiang2015]

After exiting application, the last command executed cannot be undone when application is started again. This is not mentioned in Documentation.

Steps to reproduce:

1. Execute p-add n/John Doe123 g/MALE bd/2018-12-27 bt/A+ p/98765432 e/johnd@example.com a/311, Clementi Ave 2, #02-25 t/friends t/owesMoney
2. exit
3. Open application again and run undo.

Expected:

1. JohnDoe123 patient deleted.

Result:

1. Nothing to undo

Team's Response

Accepted.

Thank you for your feedback. However, we believe that it is a common practice for many applications to get rid of any user’s history once they exit the application or else your computer may require a ton more memory space to store “junk” history after exiting any application. Therefore, undo is a command that is resetted after every exit of the application. This could be clarified more in the UG, we apologise for the gap in information.

:question: Issue severity

Team chose [severity.VeryLow] Originally [severity.Low]

• [x] I disagree

Reason for disagreement: I personally think severity should be Low because this flaw does affect usage in rare occasions, for example, after my patient cancelled his/her appointment, I deleted the appointment and exited the app. However 5 minutes later, my patient managed to reschedule his/her other plans and wanted to keep the appointment. In this case, if I knew that I could not undo, I would ask for all the information related to the appointment again. However, if I assumed I could undo, I would hang up the phone and try to undo my previous changes without asking for details, which will cause inconvenience for me.
