If you're shopping for a file manager, I recommend avoiding any project that incorporates a significant amount of LLM-generated code. Maybe in theory it could be reviewed as thoroughly as handwritten code; in practice that never happens.
With OpenCode, I can finally make my own terminal file manager. I borrowed the main design concepts from Midnight Commander and some behavior from NVim-Tree file explorer.
I hope you would like it, at least I do. Since this project is entirely vibe-coded, so I'm not going to accept PR from the community, but feel free to open issues and fork it.
