Enhancing the M3E Canvas editor to support diverse artboard dimensions beyond fixed phone portrait, specifically for desktop and landscape web interfaces. This directly impacts the accuracy of generated 'vibe-coding prompts' and design fidelity.

Technical Positioning

Achieving a more versatile and professional design tool capable of accurately representing multi-platform UI/UX, moving beyond mobile-first constraints. The goal is to provide accurate layout intent for generated code, making the tool relevant for broader web development targets.

SaaS Insight & Market Implications

This issue highlights a critical limitation in M3E Canvas: its initial mobile-centric design restricts utility for broader web development. The fixed 412x892 portrait frame fundamentally misrepresents desktop and landscape layouts, leading to inaccurate 'vibe-coding prompts' and design exports. The proposed solution, configurable artboard dimensions with presets, directly addresses this by enabling accurate representation of diverse viewports. The staged implementation, already progressing, demonstrates a clear roadmap to expand the tool's applicability. This evolution is essential for M3E Canvas to transition from a niche mobile sketching tool to a more comprehensive platform for generating multi-platform UI code, significantly broadening its market appeal to developers building dashboards, landing pages, and admin applications. The focus on consistent application across rendering, export, and prompt generation ensures a cohesive user experience and reliable output.

Support desktop and landscape web artboards

### What are you trying to do

I would like to use M3E Canvas to sketch desktop and landscape web interfaces, such as dashboards, landing pages, and admin applications.

Although the generated prompt can target Web, the editor still uses a fixed 412 × 892 portrait phone frame. The canvas, preview, component sizing presets, and PNG export therefore remain based on a phone-sized layout.

This makes it difficult to express wide-screen layouts accurately. A portrait phone sketch may also give the generated implementation prompt the wrong layout intent when the intended result is a desktop web application.

### What would help

It would help to support configurable artboard dimensions, initially through a small set of presets such as:

- Phone portrait: 412 × 892
- Tablet portrait
- Tablet landscape
- Desktop: 1280 × 800
- Custom width and height

The selected dimensions should be applied consistently to frame rendering, component placement, snapping, fit-to-screen behavior, preview, PNG export, and the generated prompt.

The generated prompt could also identify the intended reference viewport, for example: “Target a desktop web viewport with a 1280 × 800 reference artboard.”

A complete responsive layout or breakpoint system does not need to be part of the initial implementation. Fixed-size desktop and landscape artboards would already make the Web target substantially more useful.

Existing projects without explicit frame dimensions could continue using the current phone dimensi...

Thanks, this is a good fit for where the project is going. Yes, let's do it, in stages. **Model:** a frame has one size. Presets to start: phone 412×892 (current) and desktop 1280×800; tablet and custom later. Frames of different sizes can coexist in one document; there is no linking between a phone and a desktop version of a screen. To get both, duplicate the screen and switch it. The prompt treats same-named screens as one screen at two widths, and defaults the target to web when a desktop frame exists (an explicit Android target treats desktop frames as a landscape tablet). **Where the switch lives:** a connected button group on the frame label (and in the frame inspector), not a global setting. **Stages:** 1. Size on the frame. Add `w` / `h` to `Frame` (missing = phone, so old files keep working) and route every `PHONE_W` / `PHONE_H` use through it: `frameRect`, frame rendering (no phone bezel on desktop, a plain rounded rectangle), snapping, fit-to-screen, new-frame placement,...

Stage 1 is in: is merged, thank you. On top of it, 435e63b adds what came out of trying it: - Switching a screen lays it out again by the tidy rules (bars on their edges, the FAB in its corner, the rest flowing from the top) and moves the screens to its right over, so nothing lands outside or overlaps. The view stays put. - Every screen keeps the bezel; desktop only has flatter corners. The switch sits in the label in place of the icon. - The prompt target follows the screens (web once a desktop screen exists) unless the author picked one, and the target line and screen headings are written per viewport in all three languages. - The preview cross-fades between screens of different sizes and no longer rescales mid-swipe. Next, stage 2: the navigation rail and the desktop-specific layout rules. We will take that here.
