I use a bookmark to quickly change the explorer URL from .io to .deth.net. This opens the contract code in a web based Visual Studio environment. It works from any explorer (ie. EtherScan) page as long as the contract is in the URL.
While browsing smart contract code on Etherscan just change URL from .io to .deth.net. This will open Visual Studio Code instance and fetch the verified code using Etherscan API.

Drag the link below to your bookmarks to add the script. Use it by simply clicking the bookmark whenever you are on EtherScan.
You can also use the bookmark below, this works from any website where the contract is in the URL, instead of only explorer URL’s.
