⚠️ Vim mode conflicts: Some key bindings may conflict with Vim mode. Check keymap.json

⚠️ LSP installation: Language servers must be installed separately (rust-analyzer, typescript-language-server)

⚠️ Format on save: May conflict with linters if both modify code. Use one or the other

⚠️ Extensions API: Still evolving, some extensions may break between versions

⚠️ Multiplayer privacy: Shared sessions expose your workspace. Be careful with sensitive data

⚠️ Git integration: Requires Git installed and accessible in PATH
