I like it! We made something very similar at work (a "dashboard" to keep track of review status for the team). Seems a missed opportunity to me that github doesn't have something similar.

There is definitely a need for this, great idea!

Looks like there is a TLS cert issue on the public instance, but I'll be sure to check back in a couple days and check it out.

GitHub projects solves this for me.

I wanted to do something like this as a TUI, but was annoyed that the API for handling notification states was not available. I.e. you can't mark a PR as done and then actually search that status or detect it in the API results. That was somewhat annoying. I see this kinda side steps that by keeping state locally and doing a bunch of things to work out whether you're the next action... I like it :)
