Obsidian has a plug in for this… here is an announcement from the plugin author: https://www.reddit.com/r/ObsidianMD/comments/1bsa6dy/alpha_release_of_my_handwriting_plugin_ink/ (sorry for a reddit link)

Switched from Onenote to obsidian. There was a small learning curve and I had to install some plugins, but I love it. It looks amazing and runs so much faster than OneNote ever did.

It seems like the most significant new feature is called anti-gravity which is kind of an allow list?

We’ve had white lists for a long time so I’m not exactly sure how this will impact the system. That being said I read through the release notes and there are a lot of changes and improvements throughout the system, so congrats to them team on the 6 release.

I’ve had pihole running on my home network for years and I love it.

I’m not completely sure if the post you replied to was sincere based on its tone but appreciate your well reasoned comprehensive analysis.

This. I had the same situation being put behind CGnat and told them my security webcam needs port forwarding from outside and they had me back to a public IP within minutes.
