-//! ## Goals
-//! - Opinionated Subset of Obsidian. Only the things that cant be done other ways in zed
-//! - Checked in .zp file is an sqlite db containing graph metadata
-//! - All nodes are file urls
-//! - Markdown links auto add soft linked nodes to the db
-//! - Links create positioning data regardless of if theres a file
-//! - Lock links to make structure that doesn't rotate or spread
-//! - Drag from file finder to pando item to add it in
-//! - For linked files, zoom out to see closest linking pando file
-
-//! ## Plan
-//! - [ ] Make item backed by .zp sqlite file with camera position by user account
-//! - [ ] Render grid of dots and allow scrolling around the grid
-//! - [ ] Add scale property to layer canvas and manipulate it with pinch zooming
-//! - [ ] Allow dropping files onto .zp pane. Their relative path is recorded into the file along with
