I would like to suggest saving and display of the previous password on the account edit screen. I've had the situation where I hit OK but not finished applying changes to the web account then had to cancel out. My only recourse is to save, go to a backup, find my old password, restore my current and reset the password. The display of the old password would save doobs like me.
Sorry about posting suggestions on the help list. Just getting familiar with SP (it is great) and the forum.
