v17.5 - Added Features and Functions, Storage Overhaul & Performance Update

This update focuses on performance and removing storage restrictions and added Tasks, Zen Mode, Bulk and granular source selection.

💾 New in v17.5: Storage & Performance
Local-First Storage Engine: Data is now saved exclusively to Local Storage.
No More Limits: Organize as many folders as you need without hitting Chrome's sync storage limits.
Faster Performance: Saves happen instantly with no network latency.
Expanded Search Index: The Deep Search index is now capped at 5MB, allowing for significantly more content indexing before old entries are removed.
Smarter Memory: Optimized cleanup processes to reduce memory usage when switching notebooks.
⚖️ License Change: Switched from MIT to GPLv3. This ensures the project remains free and open-source forever.
✨ Recently Added
Task Manager: Integrated to-do list with priority flags and sorting.
Zen Mode: Focus toggle to hide AI chat/sidebars.
Advanced Source Control: Master "Select All" button and bulk folder checkboxes.
Self-Healing UI: Automatically repairs the folder tree if NotebookLM refreshes the page.
🔧 Technical Guide & Limitations
Storage & Backup

Device-Specific Data: Because v17.5 uses Local Storage for unlimited capacity, your folders live on the computer where you created them.
Moving Data: To move your setup to another computer, use the Export button to get a JSON file, then Import on the new machine.
Clearing Data: If you clear Chrome's "Site Data/Cookies," you will lose your folders. Export backups regularly.
Known Issues

Studio Items: Certain "Saved Responses" (citations saved from chat) in the Studio panel cannot currently be moved to folders. Only standard written notes are fully supported.
Underlining: Text underlining in notes is not persistent (this is a Google NotebookLM limitation).
