Show HN: Zenkan – Drag and drop your notes in flexible nested boards

Zenkan is a personal note-taking app with a 3-level nested board system. You can drag, resize, and arrange your notes and tasks in a flexible canvas with Markdown support (H1/2/3 titles, center text, code blocks, etc) for rich text formatting.

I created this app because I found myself a bit overwhelmed with Notion's complex and rigid databases (especially their kanban view), while also thinking that Google Keep was not structured enough for my needs.

Zenkan is a bit in the middle, I tried my best to add a nice drag-and-drop feel to it (also some satisfying sounds) while enforcing a nested structure for the cards. Zenkan can serve both as a Kanban for tasks and as a way to group related notes in a very visual way.

Let me know if you have any questions or suggestions!
