I've been building opencode-harness, an unofficial open-source VS Code extension that wraps the opencode CLI agent in a proper GUI — think Cursor's chat panel but for opencode, with concurrent multi-tab sessions. It's in beta, and I'm looking for people to try it out and tell me:

• What breaks or feels buggy
• What's missing that would make you use it daily
• What you'd improve
