Export entire folders and batch export chats in multiple formats

Currently, TypingMind only allows exporting all chats in bulk in a proprietary format (for re-importing into TypingMind) or exporting individual chats in human-readable formats like .md, .txt, PDF, HTML, etc.
This makes it slow and tedious to back up or archive whole folders/projects, or to export a selection of relevant chats, especially for users who manage many chats and projects.

I suggest adding a feature to:

• Export a whole folder (including all its contained chats) in one step.

• Allow batch selection of chats to export them together.

• Choose export format (.md, .txt, PDF, HTML, JSON, etc.) for all selected chats/folders.

• Ideally, preserve folder/project structure in the exported files.

This would make backup, information migration to other platforms, offline review, and organization/categorization of data much easier—especially for advanced users.

Additionally, it would be great if the batch export allowed filtering by favorites, date, tags, or projects, not just “all” or “one-by-one”.

Thank you for considering this improvement—it would save significant time and help ensure the safety and portability of user data!
