Canvas Notebook 2026.7.3.1

Highlights

• Streaming AI drafts for email compose, reply preview, and message summary with live status events (reading_context, writing, ready) surfaced in the compose dialog and message viewer for both quick and workspace-agent modes.
• Live draft delta rendering so AI-generated email text appears incrementally while it is being written.
• Multi-account email flows now support switching between accounts without losing per-account folder and message state.
• Faster workspace file tree loading.
• Fixed mobile markdown toolbar viewport so the toolbar stays visible during mobile editing.
