I’ve tried this plugin (I’m not the creator) and it’s really fantastic.
Allows you to manipulate Google Tasks from Obsidian. It is certainly a bit cumbersome to configure but following the steps of the creator, you get it.
Why do I share it? With only one goal: Let other developers explore it and grow.
I think it has the potential to be a good bridge between Markdown’s plain text To-Do’s and Obsidian’s tasks. It’s possible that it could be complemented with other plugins like Tasks.
