Styling and themes

Style one object in the Inspector, then spread that style across the diagram with copy/paste style, the eyedropper or a theme.

The Inspector

The Inspector on the right edits whatever is selected. With nothing selected it shows document properties instead: title, author, canvas size, grid, units and rulers. Canvases themselves are renamed from their chip in the canvas bar, not here.

For a selected shape it offers:

• Fill: shape kind, fill colour, an optional gradient, and opacity.
• Stroke: border colour, width and dash pattern.
• Shadow: a drop shadow toggle with its parameters.
• Text: font, size, weight, alignment and colour for the label.
• Geometry: exact position and size in the document’s unit.
• Action: a hyperlink or other action the object runs.

Select several objects and the Inspector header reads Multiple Selection; every style edit then applies to all of them at once.

Reusing a style

Command	Shortcut	What it does
Copy Style	⌥⌘C	Picks up the style of the selected object: fill, stroke, shadow and text, without its geometry or label.
Paste Style	⌥⌘V	Applies the copied style to every selected object.
Style Eyedropper	⌥⌘I	Turns the pointer into an eyedropper: click a source object to pick up its style, then click each object you want to paint. Choose the command again, or press ⎋: to turn it off.

Note

To restyle a whole category at once, select one representative object, open Edit ▸ Find and click Select similar style. Every object sharing that style joins the selection, and a single Inspector edit changes all of them.

Themes

View ▸ Theme applies a coordinated palette to the whole diagram in one undoable step. The built-in themes are Cool, Sunset, Forest, Mono and Vibrant.

Each theme appears in two sections, and the difference matters:

Section	Effect
Apply: Keep My Colors	Colours only the objects you have not deliberately coloured. Anything you or the AI assistant styled by hand keeps its colour. This is the safe choice for an existing diagram.
Recolor Everything	Overrides every shape and connector, discarding hand-picked colours. Use it to reset a diagram to a clean palette.

The chosen theme is remembered with the document, so new objects pick up matching colours. Both variants are a single undo (⌘Z) away.
