Canvas and code, together

The window is a canvas, a layers-and-inspect sidebar, and a code view that can sit underneath.

• Select, move, and resize on the canvas; Shift-click to add to the selection
• Node tool for path points, with a marquee for several at once
• Rectangle, ellipse, line, polyline, polygon, path, and text
• Code view shows the live source, with a Diff against the opening baseline
• Sync Selection highlights the matching markup when you click a shape, and the other way around
• Tidy Markup reindents without changing meaning
• Parse errors list line and column; the canvas keeps the last good tree

Layers that are the document

The outline is the SVG tree.

• Drag to reorder; copy or move
• Group (⌘G) and Ungroup (⇧⌘G)
• Lock, hide, duplicate (⌘D)
• Paste into Group keeps local coordinates
• Bring to Front, Forward, Backward, Send to Back
• Expand or collapse an item, its descendants, a level, or the whole tree

Inspect and arrange

Select a shape and the inspector shows what the source actually says.

• Type, id, and class
• Fill and stroke: Automatic, None, Color, Current Color, with opacity
• Geometry fields for rect, circle, ellipse, and line; point tables for paths
• Rotate, scale, flip, and ±90° around the selection centre
• Align two or more; distribute three or more
• Existing transform stacks and group-local coordinates are kept

Snap, grid, nudge

• Grid styles: Gridlines, Centre Dots, Corner Dots, Crosshairs
• Snap to grid, guides, and shapes—in local units inside a group
• Hold ⌥ while dragging to suppress snap
• Arrow keys nudge; ⇧ and ⌥ multiply the step
• Settings remember grid, snap, and nudge defaults

Paths and text

• Close (⌘J), open (⇧⌘J), join (⌥⌘J), reverse winding
• In-place text editing: Return commits, Escape cancels
• Nested text markup stays in source until you edit it there
