You can write code blocks with a special syntax that makes silverbullet interpret the code block as a script and executes it. It’s referred to as space script in the documentation iirc. You can add commands, text transformers, etc with ease.
The live query templating system is super neat too, I have a few subsections in my notes with an index page that automatically lists all child pages with a summary of the page, if I’ve written one for that page.
I plan on not celebrating my birthday and only bring it up if conversation happens to lead there, or if somebody asks. Usually somebody remembers and offers a dinner or to hang out. Not a fan of big parties! Too much hubbub.
