Canvas
Canvas is a spatial workspace for notes, files, and connections. Canvas documents are portable .canvas files that live beside your Markdown.
Why it exists
Some problems are easier to understand as a map than as a list. Canvas gives you room to arrange ideas without locking that arrangement inside a proprietary format.
When to use it
Use Canvas for project planning, research maps, architecture diagrams, and questions where sequence or proximity matters.
Workflow
Open a canvas → add note cards → arrange by relationship → link edges → return to the underlying Markdown to deepen the ideas.
Example
Question → evidence → decision → implementation note
OpenOnyx tip
Make each card answer one question. A canvas becomes clearer when cards have a single job.
OpenOnyx common mistake
Do not use Canvas as the only place an important idea exists. Put durable conclusions back into a Markdown note.
