I think if Obsidian allowed a plugin to create this feature, I would be okay with it. But personally, I would prefer this not be implemented, just for privacy purposes. People who know much more than me will probably agree with you that it is fine, but I think some people who wouldn’t be using this feature anyways might prefer things stay how they are. In fact, I didn’t know other apps couldn’t access the Obsidian folder in a way that is commonplace for other Obsidian like apps. I was happy to hear this.
Still, I hope something gets implemented that you are able to accomplish this. Good luck.
Thanks.
