For some sites i would love to be able to "lock" them in order to prevent further modifications.
I have the problem with a site with very bad designed forms where lastpass always asks me if i want to update site information.
And the problem is that if i click "yes" by mistake, it also saves some fields that are not the login/password couple, and then future forms inputs are scrambled.
So i'd love to be able to say "okay, i saved y password and my login and i don't want laspass to ask me to update it or to store any field automatically but only if i edit it manually"
it would be veeeeery useful (in y case, of course)
