Looks good!

There is a difference between the pen-pot tho. In the design, there can be two rows in each component. A type and a name (or ref in the case of an include). The type should be small and bold while the name would be larger. Is there is no name, the type should be the same styling as the name would've been.

Also, I think elements should just be called components.

Also, I think each component should be clickable to configure it, even if it has a button to go to the studio. That makes it easy to rename an adapter for example or to delete it.
