The canvas starts acting on its own. Blocks can now listen for events, run on a schedule, and take action — no user session required.

New features

⚡ Webhook Block
Drop one on the canvas and it becomes a live HTTP endpoint. Any service capable of sending an HTTP POST — CI pipelines, form backends, payment providers, monitoring alerts, internal scripts — can drive it. Set conditions to filter events, choose what happens on a target block (change its visual state, update its color, create a Kanban task, prepend text to a note), and the block handles the rest. The endpoint URL and signing secret are shown inline. Last trigger time and status are visible at a glance. Runs server-side 24/7, no open browser required.

🕐 Cron Block
Same action set as the Webhook Block, but fired on a schedule instead of an event. Pick a preset (hourly, daily at 9 AM, every Monday morning) or write a custom cron expression. The job runs on the server — it doesn't need anyone logged in.

LaTeX Block
Write and display mathematical notation directly on the canvas. Use $...$ for inline expressions and $$...$$ for display equations in edit mode, then switch to preview to see them rendered. Supports Vim mode and the same Ctrl+P shortcut as the Note block.

🔐 Proxy / Header Authentication
A new authentication mode for self-hosted deployments behind a trusted reverse proxy (nginx mTLS, Traefik, Authelia, and similar stacks). When enabled, Ideon reads the user identity from configurable HTTP headers set by the proxy and signs in automatically — no OAuth round-trip, no password flow. All sign-in and provisioning events are recorded in the audit log.

Edge resize handles
Blocks can now be resized from any edge, not just corners. Edge handles resize in a single axis only and snap to neighboring block edges with the same alignment guides as dragging. Hold Shift to disable snapping.

Under the hood

• Server-side webhook and cron execution engine — no client connection required for triggers
• {{payload.field}} template resolution for passing incoming data into block actions
• Proxy auth header parsing integrated into the request pipeline, with full audit coverage

What's next

More event sources, richer condition logic, and actions that write back — closing the loop between what happens outside and what the canvas reflects.
