More instructions could be added to the `clear` feature

[vanessaxuuan]

In the UG, the clear feature has the following documentation

However as clear removes ALL data and it cannot be undone, new users who have added all their contact details may execute clear by accident/due to curiosity and they will have to manually add everyone back to UniGenda again.

Perhaps a warning or explanation as to why clear should be used with caution could be included to help the users to avoid accidentally removing all their contacts.

Team's Response

Technically, a user should understand what a command do before using it. After all, that's what UGs are for. So, we argue that this should be a severity.Low as not having such warnings will only affect those "curious" users who did not read the UG thoroughly and should only happen in rare occasions.
