What problem does your feature solve?

Working with a group of contracts. Want to see contract names.

What would you like to see?

On the Contract Explorer page, if a contract has already been labeled in Saved Smart Contracts, display the user-assigned label/name directly on the page to improve contract recognition and navigation.
