V4 New Feature Examples?

Just now going over features in V.4 and noticed, “layout blocks”. Sounds intriguing, and I read the page about it but I need a visual example to see how it works and what’s possible.
Is there an example of this somewhere - maybe on the new Sparkle hompeage?

There are a few other new features with documentation but no real in-use example - I’ll need to re-read those sections to outline what I’m trying to learn.

the balloon template have almost everything structured with layout blocks - easy to get how they work there, and they’re really simple

I don’t see a template for that anywhere, just the live example on the Sparkle site.

I mean, think you have unchecked the “show template picker” on preferences maybe?

Totally forgot about the built-in templates!!! Thx
