The other thing is, I've had "computer use" on my LLMs since way before they had vision and macos integration. Since in TUIs both control and data is text, they can simply send text to a pty.

There is an opencode plugin for this opencode-pty.

Terminals + browsers is all I want for most apps.

Native GTK/QT is really good, but I only want it for "system" things like a clipboard manager or file manager settings app and things like that.
