Documents Gets a Navigation Pane, a Status Bar, and a Focus Mode

Drive's Documents editor picks up three related pieces of editor chrome this release, closing gaps that were measured directly against the production editor beforehand: there was no way to jump to a heading, the bottom of the editor was 36 pixels of empty space plus a zoom slider, and none of the three rows of toolbar and menu chrome above the page could be put away.

Outline panel

A new outline reads document headings — both Drive's own heading markers and the ones the underlying Univer engine writes — into a clickable list with their positions in the document. It's the first item in the editor's side rail; the heading currently under your cursor is highlighted, and clicking an entry jumps the selection there. If a document has no headings yet, the empty state tells you how to add one (via Home ▸ Styles) instead of just showing nothing.

Status bar

Where Univer's own footer sat empty, Documents now shows which page your cursor is on out of the total page count, a word count that opens into a dialog with word/character/paragraph counts and reading time (plus the same numbers scoped to your current selection), and zoom controls with presets and a "Page width" option.

Focus mode

A new View ▸ Focus option (reached from Univer's own tab, since the menu bar doesn't always carry a View menu) hides the menu bar, the side rail, and Univer's toolbar, leaving just the page and a small "Focus · Esc" chip in the status bar. Pressing Esc exits.

Verification

This shipped with 30 new tests written and confirmed failing before the implementation, plus the full Drive suite (1,092 tests), a clean typecheck, a green guardrails run, and a successful Cloudflare build.
