Cool! I tried Nate’s theme component on my personal site, and it does what is on the tin. Very nice job and implemented quickly too! 
To be able to use it here, we’d have to be able to limit it to a category. If we decide this approach works well, we’d also want to be able to create more than one button.
FYI, Sam is also working on an experimental implementation that is different and much more flexible, using automation.
