Problem Statement

Feature Request

Please add support for Korean (한국어) as a UI language option in Claude Code.

Currently, the interface (including the left project list panel) is English-only.
Many Korean users would benefit from being able to use Claude Code in their native language.

Would love to see language localization support, especially for:

• Left sidebar / project list
• Menu items and labels
• Settings interface
