Hi 병민, thank you for your feedback. We appreciate your suggestion to add South Korean language support and have shared it with our team for consideration.

As for your second request, we’d love to make sure we fully understand what you need. Are you hoping to add multiple sub-goals under a single parent goal? If you could share a bit more detail, it would really help us ensure we’re guiding you in the right direction. Looking forward to your feedback!
