I’ve found a pretty good alternative method. It involves converting cards into markdown files, which allows us to edit cards in markdown without significant lag. I would like to recommend the plugin at GitHub - slnsys/obsidian-canvas2document: Plugin for Obsidian to convert a complete Canvas to a long form document. It’s excellent for converting cards into markdown files. Currently, it hasn’t been updated to sync to the canvas, but the developer has stated that this feature will be included in the next few updates. I’m very grateful for this plugin.Now released 1.2.0 of Canvas2Document with full support of complex hierarchical structures, ordering and metadata for navigation
By the way, @WhiteNoise, do we have any plans for canvas performance optimization at the moment? Or is there any specific test that I need to provide?
