ConEmu Extensions ​

Extensions originated by ConEmu (now superseded by Windows Terminal on Windows). ConEmu defined several OSC 9 subcommands for progress reporting, desktop notifications, and tab manipulation. The OSC 9;4 progress bar protocol has been widely adopted across platforms — Ghostty, iTerm2, Windows Terminal, WezTerm, Konsole, and mintty all support it, making it one of the most successful cross-terminal extension adoptions.
