Anyone know of a Chrome extension that keeps the current path but toggles through a list of development/test/staging domains?
No, but we can build one!
This is not complete, it's not efficient, but it works.
Get it from the Chrome web store; https://chrome.google.com/webstore/detail/domain-swap/ngiiihlebepigjbefembddhdplmaghep
Visit the options page
Add a domain set and save it
Visit one of the sites in the domain set
Click the button
Use the links to jump to another domain with the same path
