Why a Ribbon Toolbar at All

GridDoc is doing something unusual under the hood — a spatial canvas, live formulas across blocks, handwritten equation solving. Layered on top of that, the editor surface looks deliberately familiar. The reason is simple: people who write engineering reports and analysis memos already know the ribbon. Asking them to relearn how to bold a heading or insert a chart is friction with no payoff.

So GridDoc keeps the ribbon. What's behind each tab is what changes.

The Tabs

The ribbon runs across the top of every document and is organized by what you're trying to do, not by which feature lives where:

• File — open, save, print, page setup, export
• Home — fonts, alignment, basic formatting, clipboard
• Insert — block types: Calc Block, Text Box, Table, Chart, Diagram, Image, Note, Sticky Note, Freehand
• Draw — pens, highlighters, eraser, freehand strokes, the entry point for Draw to Solve
• Layout — page setup, orientation (Portrait / Landscape), margins, the toggle into Book View
• Data — formula tools, calculation controls, Auto Calc, references across blocks
• Tools — utilities for working with the document (lasso, snap, gridlines, alignment helpers)
• View — zoom, gridlines, panel visibility, switching between the spatial canvas and Book View
• AI Tools — assist features that operate on the current selection or block
• Help — documentation, shortcuts, contact

The active tab is highlighted; switching tabs swaps the contents of the panel below without leaving the document. There's no modal dialog, no separate workspace — the canvas stays in place and the controls change around it.

The Quick Access Toolbar

Above the ribbon sits the Quick Access Toolbar (QAT) — a compact strip of the actions you reach for constantly: save, undo, redo, print, and a small set of others. It stays visible no matter which ribbon tab you're on, so the round trip for "undo that, save, keep going" never costs you a tab switch. For engineers iterating on a calculation, that's the difference between the editor staying out of your way and getting in it.

Collapse Ribbon

When the ribbon is doing its job, it's a navigation aid. When it's not, it's vertical space the canvas could be using. Collapse Ribbon hides the panel and leaves only the tab bar visible, giving the document back roughly half a row of screen real estate. Click any tab and the ribbon expands temporarily; click into the canvas and it collapses again. Expand Ribbon pins it back open.

This matters most on smaller screens and during long writing sessions, where the canvas — not the toolbar — is the thing you want to see.

The Formula Bar

Sitting just under the ribbon when a Calc Block is selected is the Formula Bar, working the way it does in any spreadsheet: it shows the formula behind the selected cell, lets you edit it directly, and gives you the full expression even when the cell only displays a result. If you've used Excel, this is the surface you already know — the difference is that the cell in question can live anywhere on the canvas, and the formula can reference cells in other Calc Blocks across the page.

What This Buys You

The ribbon itself isn't the feature. What it buys you is the absence of a learning curve on the parts of GridDoc that don't need one. Inserting a chart, changing a font, adjusting margins, switching to landscape — these work the way you expect, where you expect to find them. That keeps your attention free for the parts that are new: the spatial layout, the cross-block formulas, the live solving.

A familiar surface, exposing unfamiliar power. That's the whole point.
