 - [x] ~~**M5 — Ship infrastructure.**~~ Custom icon, version bumped to 0.1.0, `scripts/release.sh` for one-shot tag+upload, README install section. Done 2026-05-22. **Next step (user action):** run `pnpm tauri build` on Windows then `scripts/release.sh v0.1.0` from WSL to cut the actual release.
 - [ ] **Native Windows shells (cmd / pwsh)?** `portable-pty` supports them for free; keep the option open. Decide whether to expose in UI at M3.
 - [ ] **Persistent scrollback across app restarts.** Would need an out-of-process mux daemon. Big scope creep; explicitly deferred past v1.
-- [ ] **Code markup / syntax highlighting in-app (VSCode-style).** User idea 2026-05-28 — "would be kind of neat." Two readings, different feasibility: (a) **highlight code in terminal output** — not really doable in xterm.js; it renders raw bytes/ANSI and has no concept of "this region is Python." Would need to detect code blocks and re-emit ANSI color, which is fragile and fights TUIs like claude that already color their own output. (b) **a dedicated editor/viewer pane type** alongside terminal panes — embed Monaco or CodeMirror as a new LeafNode kind, open a file from the pane's cwd, get real VSCode-grade highlighting + read/scroll (maybe edit). This is the tractable version: the layout tree already supports heterogeneous leaves, so it's "add a non-xterm pane kind" rather than reworking the renderer. Scope: pick editor lib (CodeMirror 6 is lighter than Monaco for an embed), file-open IPC over WSL paths, decide read-only vs editable. Defer — nice-to-have, not core to the multi-terminal purpose.
 - [ ] **Keybinding philosophy.** Copy tmux, copy WezTerm, or invent? Decide at M3.
 - [ ] **Help (?) overlay.** Small `?` icon in the titlebar, opens a modal listing all keyboard shortcuts (split / close / promote / broadcast / palette / font size / nav) and quick tips on shell-picker dropdown + SSH host manager + saved-password autotype. Same modal style as `Palette` / `HostManager`. Source of truth lives in one place — refactor the README shortcuts table to be generated from it (or vice versa) so they can't drift.
 - [ ] **MCP server: Claude controls tiletopia.** Expose a Model Context Protocol server (stdio transport, runs inside the Tauri app or a sidecar) so a Claude session — running anywhere, including inside one of tiletopia's own panes — can drive the workspace. Capabilities to expose as MCP tools / resources:
