import/export to other notion providers

[Vicentesan]

sealnotes currently lacks the ability to export notes to or import notes from other popular note-taking applications. adding this functionality would enhance user experience by allowing seamless migration between platforms while maintaining sealnotes' core value of encryption and privacy.
proposed feature

implement export/import capabilities for popular note-taking platforms including:

• notion
• obsidian
• evernote
• standard markdown files

user benefits

• easier migration path for new users coming from other platforms
• flexibility for users who work across multiple note systems
• prevents lock-in while maintaining security

technical considerations

• maintain end-to-end encryption during export/import process
• handle rich text formatting conversion appropriately
• respect each platform's api limitations and requirements
• consider implementing a standard format (like markdown) as an intermediary

priority

medium - this would significantly improve user experience but doesn't affect core functionality

questions

• which platforms should be prioritized first?
• should we implement a universal export format or focus on platform-specific integrations?
• how should we handle formatting differences between platforms?
