In reply to Luke Carbis.

So, Luke, I built a browser extension to add a command palette to WordPress sites, and it has some other "bonus" features that allow you to carry preferences between sites. One of which is notice hiding.

You can see it in action at: https://twitter.com/TurboAdmn/status/1489897787605008384

The plugin version is a little behind the extension version. But I'll be updating it soon.
