Every tool and panel

The left rail holds the tools you draw with; the right and bottom panels hold everything you can do to what's selected.

Left rail — shape tools

Select, rectangle, ellipse, diamond, line/arrow, freehand pen, text, frame
Image (uploads and places a file), eraser, and pan
Less-frequent shapes — polygon, star, triangle, vector path, flowchart nodes (process/decision/terminal), and a handful of icon shapes — live in flyout groups off the main rail, or are searchable from the command palette.

Right panel — style controls

With a shape selected, the style panel shows fill, stroke, opacity, and corner radius by default, plus collapsible sections for effects, layout constraints, and conditional formatting. Selecting multiple shapes with different values shows Mixed rather than guessing which one wins.

Bottom bar — position & size

X, Y, width, and height, plus a corner-radius control with four modes — all corners at once, adjacent pairs, opposite pairs, or each corner independently. Every numeric field accepts simple arithmetic (type 120+8 and it resolves to 128).

Layers panel

A collapsible tree of every shape on the board, newest-drawn on top. Drag a row onto a frame or group to nest it inside; drag it onto the empty space below the tree to pull it back out to the top level. Lock and visibility toggles appear on hover.

Board header

Board name, a copy-link shortcut, the visibility badge, save status, the hand-drawn style toggle, export, and a menu with local-data controls live in the floating header at the top of the canvas.

Zoom controls

Bottom-right: zoom out, the current percentage (click to reset to 100%), zoom in, and fit-all. Zoom ranges from 1% to 6400%.
