## ExtMemo Description
[+] Unique Note Chain Architecture
- Group related notes into sequential chains, not folders.
- Connect fragmented notes into one organized thread.
- Add daily or milestone notes to track projects end-to-end.
- Track height changes and dental visits in chronological chains.
- Give each travel day its own note, with plans and bookings in one chain.

[+] End-2-End Encrypted, and Searchable
- Granular Flexible Encryption: Encrypt an entire note or only its most sensitive content.
- Chain-Wide Search: Unencrypted notes can index and search the entire Note Chain.
- Stored neither on the server nor on your device: only briefly in memory when needed for decryption.

[+] Visible Todos In Context
- Todos stay in context: Part of your meeting notes, not a separate task list.
- Simple by design: Just set a due date. No complicated setup.
- Visualize dependencies: See what to do first and what comes next at a glance.
- Organize your thoughts: Turn ideas and tasks into a visual mind map.
- Track completion automatically: Completion time is recorded automatically.
- Stay on track: Get daily reminders for todos due within the next 5 days.
- Manage time-sensitive benefits: Never lose track of unused coupons, credits, or expiring offers.

[+] Synced to Desktop (Web App), More Powerful, Maximum Efficiency
- Work seamlessly across devices: Stay in sync and handle information more efficiently on the desktop.
- Import with ease: Bring your notes into ExtMemo with JSON or Markdown.
- Export everything: Export your entire note collection in Markdown for easy access and portability.
- Explore your knowledge visually: Use the Nebula View to see semantically connected Note Chains at a glance.
- Build your todo flow visually: Drag todos into place and connect them with dependencies.

[+] Valuable & Private Information, Shared Securely
- Share entire chains: Share Note Chains securely with teammates or family members.
- Share encrypted content: E2EE-protected information can be shared without giving up privacy.
- Everyone adds their own notes: Members can add or update notes without interfering with each other.
- Keep information up to date: Multiple people can update the same chain, keeping everyone aligned on the latest status.

[+] More Features

- Cross-Chain Links: Link chains together and jump between them instantly.
- Bookmarks: Save important notes for quick access.
- Dark Mode: A comfortable experience in low-light environments.
