[Feature Request]: Google Drive "Open with" Integration for Seamless Workflow

[KoichiroHatsuse]

Feature Description

Add native Google Drive UI integration that allows users to open PDF files directly from Google Drive using the "Open with" context menu.

Proposed User Flow:

1. User finds their PDF in Google Drive (using Drive's powerful search)
2. Right-click the file → "Open with" → "Stirling PDF"
3. File opens directly in Stirling PDF, ready for editing/compression/processing

This would work similarly to how Adobe Acrobat, Lumin PDF, and other professional PDF tools integrate with Google Drive.

Why is this feature valuable?

Current Pain Points:

• The existing Google Drive File Picker (Pro/Enterprise feature) requires users to navigate through folder trees within Stirling PDF
• For users with 10,000+ folders in Google Drive, finding the correct file through the picker is extremely time-consuming and inefficient
• Users must constantly switch between Google Drive search and Stirling PDF, interrupting their workflow

Benefits of This Feature:

• Seamless integration with existing Google Drive workflows
• Leverages Google Drive's search capabilities - users can find files using Drive's powerful search, then immediately open them in Stirling PDF
• Eliminates unnecessary downloads - no need to download files locally for processing
• Matches user expectations set by other professional PDF tools
• Significantly improves UX for enterprise users with large Drive repositories
• Increases adoption by providing a more intuitive entry point

Use Case Example:
A user with 10,000+ folders needs to compress a specific PDF. Instead of navigating through folder trees in the File Picker, they:

1. Search for the file in Google Drive (fast and efficient)
2. Right-click → Open with Stirling PDF
3. Process the file immediately

Suggested Implementation

Google provides the Drive UI integration API for this purpose:

• Documentation: Google Drive API - Integrate with Drive UI

Implementation Steps:

1. Register Stirling PDF as a Drive app in Google Cloud Console
2. Configure OAuth scopes for Drive file access
3. Set up Drive UI integration with proper MIME types (application/pdf, etc.)
4. Implement callback handler to receive file IDs when users select "Open with Stirling PDF"
5. Fetch file content via Drive API and load into Stirling PDF

Reference Implementations:

• Adobe Acrobat for Google Drive
• Lumin PDF Google Drive integration
• Other successful Drive-integrated applications

Tier Consideration:
This could be implemented as:

• Pro/Enterprise feature (similar to existing File Picker) for monetization
• Community edition feature to drive adoption and differentiate from competitors

Additional Information

Related Features:

• This enhances the existing Google Drive File Picker (2946 feature request integrate file selector with google drive and onedrive #3253) by providing a reverse workflow
• Instead of selecting files from within Stirling PDF, users can initiate actions from Google Drive itself

Market Context:
Most professional PDF tools (Adobe, Lumin, PDFelement) offer this integration as a standard feature, making it a competitive necessity for enterprise adoption.

User Impact:
This feature would particularly benefit:

• Enterprise users with large, complex Drive structures
• Teams that primarily work within Google Workspace
• Users who prefer cloud-first workflows
