Lega Interface Tour

The Lega editor has four main regions: the canvas in the center, a toolbar along the bottom, a tabbed panel on the right, and a chat pane for AI generation. Once you know what lives where, moving around the editor becomes automatic. This page walks through each region.

The canvas

The canvas is the large area in the middle of the screen — this is where your frames (artboards) live and where you'll do most of your direct manipulation: selecting, dragging, resizing, drawing shapes. A single document can hold multiple frames side by side, which is useful for campaigns that need several matching sizes (see Frames & Artboards).

Viewport controls sit near the canvas for zooming and framing your view: one button fits the active frame to the window, another fits every frame in the document at once, and a dedicated control lets you create a new frame when you need more artboards.

Under the hood, the canvas is rendered by Lega's own editor engine — a command-based system with full undo/redo, not a wrapper around a generic drawing library. If you're curious how that works at a conceptual level, see the Legon Editor Overview.

The bottom toolbar

The toolbar along the bottom edge holds your direct-manipulation tools: a select tool, text tool, image tool, and shape tools (rectangle, circle, polygon, path, line — some of these live in a flyout to save space). Click a tool, then click or drag on the canvas to place that element manually.

Undo and redo buttons sit here too, mirroring the keyboard shortcuts — useful if you'd rather click than remember key combinations. See Keyboard Shortcuts for the full reference.

Worth internalizing: the toolbar is for manual placement. It's not where AI generation happens — that's the chat pane, described below. Most first drafts come from the chat pane; the toolbar is what you reach for when you want to add or adjust something by hand afterward.

The right-hand panel

The right side of the editor is a tabbed panel with three tabs:

• Properties — shows the settings for whatever layer is currently selected: position, size, rotation, fill and stroke color, opacity, typography controls for text, and so on. This is where most fine-tuning happens after a layer exists.
• Layers — a flat, ordered list of every layer on the active frame, with the ability to rename, reorder, hide, lock, and group. If you're not sure what's actually on your canvas, or you need to select something buried under other elements, this is the fastest way to find it. Full guide: Layers Panel Guide.
• Brand — houses brand-level assets like saved colors and fonts, so a design stays consistent with the rest of what you've built in Lega.

One behavior worth knowing: the Layers tab only mounts its content while it's active, and selecting a layer on the canvas automatically switches you over to Properties so you can start editing immediately. That's deliberate — the panel tries to show you the thing you need next rather than making you click for it.

For a deeper look at how layer selection and organization works, see the Layers Panel guide.

The chat pane

The chat pane is where AI generation lives — this is the "describe it and get a layout" interaction that sets Lega apart from tools with only a manual toolbar. Type a description, and the AI generates layers directly onto your active frame. You can also select an existing layer and ask for a targeted change instead of regenerating everything, which keeps the rest of your design intact.

The chat pane is conversational: each request builds on the state of the canvas as it currently exists, so you can iterate — generate, look at the result, ask for an adjustment, look again — rather than getting one shot per prompt.

Putting it together

A typical loop through the interface looks like this: describe a layout in the chat pane, review what landed on the canvas, open Layers to find a specific element, switch to Properties to fine-tune it, and reach for the toolbar if you need to add something the AI didn't include. None of these regions are exclusive — you'll move between all four within a single design.

If you haven't run through an actual first design yet, Creating Your First Design walks the whole loop step by step. And once the interface feels familiar, Keyboard Shortcuts will get you moving through it faster.
