How can I disable the bell icon/emoji from the title bar in iTerm2? I find it annoying and get no use from it. Here's a picture of what I'm talking about:
The bell is a visual indicator that the terminal bell "ringed".
You can disable it on a profile by orofile  basis in the "Preferences" pane
Menu: Profiles | Open Profiles | Edit Profiles... | Terminal
in the "Notifications" section uncheck "Show bell icon in tabs"
