Have you ever use the offline mode in chrome or set the data downloading and uploading speed.
It is the great feature in chrome. In that way you easily develop your offline site. Without disconnecting your LAN or Wifi connection.

Best way to develop offline site for developers.

Have you ever copy the the data from the console in chrome?

There is a sure way to copy the data from the chrome console. Even there is many nested objects.

I love that feature of chrome.
