Show dropdown only if you have more than one account and Copy last used account info

In the “Context Menu > Auto-Fill/Copy Username/Copy Password” items, there is always a dropdown upon hovering regardless of whether you only have one account or not.
I request that the dropdown only appear if you have more than one account, and that the last used account’s info be copied when you click the item.
Having to use the dropdown every time I wanna copy just one account’s info is inconvenient.
