Community Directory: Totonio Presentation - Obsidian Plugin
I developed Totonio Presentation to view local .totonio diagrams alongside notes in Obsidian. It works offline and provides pan/zoom, presentation-frame navigation, and Markdown previews without modifying the source file.
I’d appreciate feedback on one limitation: editing happens outside Obsidian, in a browser-based editor. The plugin’s “Open in Totonio” button opens the website, but users must select the vault file themselves and save changes back manually.
Would that workflow be useful to you, or would you expect the button to open the current diagram directly? I’m considering an optional, one-time permission to connect a diagrams folder, but that is not implemented yet.
