Ergo – 20-20-20 Rule and Ergonomic Reminders for VSCode (marketplace.visualstudio.com)

I started digging into the code, and it appears that you only have the "look away for 20 seconds" bit coded into https://github.com/s4m-mo/vscode-ergo/blob/master/src/extens... ... where are the rest of the reminders you stated?

Also, you have issues disabled on the repo, so I couldn't open an issue for this.
