Description

Hi! this question or feature has been mentioned before, but the solution is not very convenient...

See #2316 (Enable suggestion details by default) See #2241 (ExpandSuggestionDocs Settings conflict with the command panel)

Actually, I have tried a few methods and they all work.

editorDidMount={(mountEditor) => {
    const { widget } = mountEditor.getContribution('editor.contrib.suggestController');
    if (widget) {
        const suggestWidget = widget.value;
        // enable suggestion details by default
        // method 1
        suggestWidget._setDetailsVisible(true);
        // method 2
        suggestWidget._storageService = {
            ...suggestWidget._storageService,
            getBoolean(key) {
                return true;
            },
        }
    }
}

but, this may not work in a future version... so, can be exposed in a configurable way to configure or otherwise?

Thanks!
