Group dictionaries in Dictionary.app I've installed extra dictionaries in Dictionary.app. It's over 9Gb. I'd like to group them by language as is shown in the image below. I've tried to rename their labels in the app, tried editing the Bundle name in Info.plist, but it's not working (dictionaries have same name but not group). Does someone have a solution?

Unfortunately, I believe you can't group dictionaries. However, you can re-order them at will by drag-and-dropping them in Dictionary.app's preferences.
