Etherscan has launched a redesigned Contract tab, introducing an IDE-style code browser to enhance user interaction with smart contracts. The update, announced on April 9, includes features such as file tree navigation, multi-file tabs, contract outline navigation, and cross-file keyword search. Additionally, the interface for the "Read" and "Write" contract tabs has been revamped to improve user experience. The new design allows users to switch to full-screen mode and directly open fully matched contract code for editing in Blockscan and Ethereum Remix. This development aims to streamline the process of viewing and interacting with smart contracts on the Etherscan platform.
