Gmail's default rich text editor doesn't allow direct HTML editing. This extension enables users to edit email HTML source code directly, providing greater control over email formatting and styling.

1. User opens Gmail compose window. 2. Extension detects new compose editor via MutationObserver and injects 'Edit as HTML' button. 3. User clicks button to switch from rich text to HTML source editor. 4. ACE editor opens in iframe with current email HTML. 5. User edits HTML directly with syntax highlighting. 6. Changes sync back to Gmail compose area in real-time via postMessage. 7. User clicks button again to return to rich text mode.

Target users: Developers and designers who need custom HTML email formatting / Users who want fine-grained control over email HTML source / Technical users who prefer working with raw HTML / Email template creators

Cannot verify if Gmail's own login requirement affects functionality
ACE editor library contains many false positive keyword matches that required manual verification

Monetization

No paid features detected

No payment flow, subscription model, premium tier, or feature gating exists. All keyword matches for 'checkout' and 'pro' are false positives from the ACE editor library (minified code containing 'packaged', 'property', etc.). The extension provides full functionality without any payment requirements.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension operates entirely within Gmail's compose interface as a content script. It does not implement any authentication flow, create accounts, or call external login APIs. Users must be logged into Gmail to compose emails (destination service requirement), but this is pre-existing and not imposed by the extension.
