What is Squarespace's coolest feature?

I have been playing around with squarespace and have been wondering what cool features you guys use to make your sites better?

I have a 7.0 site and have had it since I became a Squarespace customer in 2015. It looks very different than it did when it first went live.

It is primarily a blog and photography site built on the Avenue Template. This is the demo for Avenue:

To answer your question I use a lot of Custom CSS to give the site a unique look. I use a drop-down menu, two blog pages, quotes, block animation, and one of the best features that Squarespace has to offer, summary blocks. I also use a feature exclusive to 7.0, a landing page. This is my site:

Depends on the look you want to achieve...the possibilities are endless. Spark Plugin has some additional features that don't require coding. SquareKicker is another one.

You can do even more with CSS. Here's several features you can add with instructions on how to implement the CSS - https://www.jessicamiller.work/blog?topic=CSS
