Closing and deleting accounts can have bad, irreversible effects in QWin, of which some users may be unaware.
I suggest adding 2 new Preferences, both with default OFF:
- Allow closing accounts
- Allow deleting accounts
If the user tries closing or deleting an account and the preference has not been set to ON, the operation should be refused with an explanatory warning message. Then the user must think about whether they really want to perform that action.
This is not to suggest that the commands to close and delete accounts should be removed or disabled, just that the commands are refused unless the preferences are set to allow them.
