Could you build this?
No Building a terminal multiplexer on top of libghostty requires low-level systems programming, terminal emulation internals, pseudo-terminal (PTY) management, and complex concurrency in C or Zig/Rust.
What it would actually take: A production terminal multiplexer requires C or Zig/Rust bindings to libghostty, robust PTY handling (termios, ioctls, signal trapping like SIGWINCH), ANSI/VT escape sequence parsing, and low-latency IPC for client-daemon architectures (similar to tmux or GNU Screen). The hard part is managing state across re-attaches, nested escape sequences, and race-free multithreaded I/O without dropping frames or corrupting terminal states. This demands deep systems programming expertise and intimate knowledge of POSIX terminal subsystems.
