(Browser extension) When selecting a LastPass entry via the right click or clicking on the LastPass icon in the field, it would be nice to be able to search in the LastPass vault for an entry, especially if no matches were found or if you are on a different site. For example, I was trying to log into VerizonWireless, but the website had presented a login page for login.verizon.com, so no matches were shown. To fix this, I would have to create a second entry in the Vault for this domain or search for the intended domain using the LastPass icon at the top of the window and copy/paste the username and password separately. Another example is when you need to enter credentials on another site, such as for linking an account to a bank - LastPass only shows the bank account site info, and it is a tedious process to copy the creds for the intended site.
I see there is a search icon on the context menu, but this only searches within the matches and not the vault.
FYI - You can do this fairly easily with the iOS app when it shows the lastpass entry above the keyboard. If it's not the one you want, you can click on the key icon and search for the entry in the vault to use.
