[Feature Request] Community Presets & Workspace Sharing: Export/Import toolbars to boost user engagement and adoption

[MahmoudhassanGX]

Vision & Community Growth

The Donut toolbar and custom presets are standout features of this project. Enabling users to easily share their unique setups will transform these configurations into a viral community asset:

• Graphic designers can share specialized "Image Optimization & WebP Toolbars".
• Legal/Office users can publish "PDF Automation & OCR Toolbars".
• Content creators can showcase their workflow setups online (Reddit, GitHub Discussions, YouTube tutorials, and blogs).

By making presets and toolbar modes effortlessly exportable and shareable, the project encourages word-of-mouth adoption, drives new users to download the official release, and builds an active community around custom workflows.

Proposed Features

1. Exportable / Shareable Preset Bundles (.json)

• Provide a single "Export Preset / Workspace" button in the Donut Toolbar settings.
• Generate a compact, shareable .json preset file containing the wheel mappings (Front/Back slices), custom rules, and associated format settings.
• Include an "Import Preset" button to load any community-shared file instantly with one click.

2. Web-based Preset Hub & Visual Configurator (Optional / Future Growth)

• Host a simple web builder on the project's landing page where users can visually arrange their Donut toolbar and download the .json file to load into their app.
• An official "Community Presets Showcase" linking back to the GitHub releases page, boosting project visibility, stars, and direct official downloads.

Why this matters for the project:

Instead of keeping configurations locked locally, turning them into a shareable format makes the app a topic of discussion among creative and professional communities, driving steady traffic and official downloads.

Thanks! This is the same as #677, so let's keep the discussion there. Export / import of presets and donuts is in Settings → General → Presets and toolbars.
