"Replace All" function

Love the app. One small feature request though: Can you add a “replace all” function? If I am not overlooking something, items can only be “replaced” on a one by one basis at the moment.

It’s not that urgent though. Right now, I can use a second app, e.g., Atom or TextEdit to achieve this. However, such a feature would make FoldingText even more convenient :slight_smile:
