I hope Obsidian can specifically add a visual preview view for the canvas, such as a canvas file list view, where we can view, preview, and manage all the canvases, similar to what is available in Logseq and Figma. The visual management view might be more suitable for the whiteboard. Please refer to the attached image for reference.
Canvas Visual Management Interface，you can preview the canvases inside it.
