Top request for me is linking Secure Notes to a Site's record. For example, if I have notes for 2 credit cards and 2 bank accounts all associated with a bank Site's login, it would be great to "group" or "link" those secure notes underneath the login for that bank.
This goes for other accounts (insurance, investment, membership, etc.) where I've entered my detailed account info in a secure note, but there is also a Site login associated with that account. Currently these are 2 separate records entirely, but if they could be linked/grouped it would be much more organized and convenient.
This same request has come up in a few other posts already:
My other main request is the ability to have 2FA be able to send messages to more than 1 cellphone. If I am using Identities to share the same LastPass account with wife, since we have so many overlapping accounts, it would be good to send the 2FA text to either/both phones when doing a login. Same goes for if I have a work cellphone and a personal cellphone, and I'm not always carrying both with me.
