# UI and interaction parity

> **Last reviewed:** 2026-10-10 · **Last updated:** 2026-10-11 · **Change:** minor (column select #740, multi-object move #844, Shift-⌘-G #810 fixed) · **Target:** Adobe Acrobat Pro (Acrobat DC, continuous track 26.002.21931, macOS)

How PdfCraft's tools, panels, shortcuts and feel compare with Acrobat Pro's current interface (the
2023+ "new Acrobat": All tools pane on the left, quick-action toolbar, Home view). Behaviour is
observed clean-room (`plan/acrobat/02-ui-ux.md`, local-only; `AGENTS.md` §2); nothing from Adobe's
interface is copied. Gaps ranked in [gaps.md](gaps.md).

**UI/UX fidelity ≈ 55% ready** (estimated), **30–60 h** additional to the features total.

## Measured

- **184 registered commands** (`crates/engine/src/commands.rs`), every one in the menus, the
  command palette and the automation `command_run` tool; menus are generated from the registry
  (`view.menus-from-registry`).
- **141 automation tools** (`crates/automation/src/tools.rs`), so every UI action can be checked
  headlessly.
- **View area of the checklist: 62.5% breadth** (52 shipped, 11 partial of 92).

No dump of Acrobat's menu tree has been diffed against the registry yet (gap 24).
