What is the best way to update Cursor editor preferences like font size and auto-save?▼

The best way to update Cursor editor preferences is by modifying the user settings.json file, which allows you to deterministically apply configurations like font size, themes, auto-save, and tab size.

Does Cursor settings.json support comments when applying configuration updates?▼

Why does my Cursor editor not reflect new settings.json changes immediately?▼

Your Cursor editor might not reflect new settings.json changes immediately because certain editor preference updates require a Cursor or VSCode restart to take effect, which should trigger a user notification.
