Rename "Add label to conversation" to "Copy conversation"
Info: I'm using Geary with my own IMAP server (Dovecot).
Under the hood "Add label to conversation" copy the message. So why is it named "Add label to conversation" and not ex: "Copy conversation"? I think it is a bit confusing, but maybe that is just me?
Maybe Geary should use IMAP keywords/flags to store the labels? (https://stackoverflow.com/questions/3632102/imap-custom-keywords)
