I am changing the font size in the script editor settings, but when a new script editor is opened, the font size jumps back to default. Is this a bug or a feature?
This looks like a Script Editor preference-persistence issue rather than intended behavior.
As a workaround, Ghost Writer lets the Grasshopper C# or Python component be edited in an external IDE, so font size, theme, keybindings, extensions, and other editor preferences are managed by VS Code, Cursor, Zed, or whichever editor you choose. Saving still updates and recomputes the component in Grasshopper.
This does not fix the native Script Editor setting itself. Disclosure: I’m the developer of Ghost Writer.
