How to save and reuse elements in future projects?

Are there any tools or ways In Webflow to save design elements and sections you’ve worked on to a library that can be used as assets and templates in future projects? This would resemble Wix’s “My Designs” feature or the same in Elementor.

I often refer back to previous projects and/or I have a sandbox site that I save stuff to.
With two Webflow windows open in the same browser, you can then copy and paste components from one project into another.
