IMHO, it's still far from GA quality/usability. A must-have feature that's missing is a toggle switch that lets you temporarily turn it off. Without a feature, it can get really noisy.
The VSCode extension has one. There's a button in the bottom right with the logo that you can click to enable/disable, or you could add a keybind for the "github.copilot.toggleCopilot" command
This may vary in the IDEs they support, but theres an "Activate Copilot" toggle button right in the status bar in VSCode to toggle on and off instantly that appears on every editor window if the extension is installed.
