Added
atrium registers in Finder's "Open With" menu for common file types and folders — files open in a new editor room, folders activate or create the matching workspace.
Notepad supports subfolders — right-click a workspace to create one, drag notes between folders, or move via the note context menu.
Adapter panes (Claude, Codex, Gemini) gain a collapsible markdown composer below the terminal — write multi-line input with formatting, ⌘⏎ sends.
atrium note canvas-patch <id> streams JSON Patch operations into a canvas note so agents can render it live in the user's open notepad pane.
