This extension can perform two operations: 1. Save a list of all open tab URLs from a Chrome window to a text file. 2. Import URLs from a list and open them in individual tabs in the chrome window. You can save the text file under a specified name. There is a text field that gives you the flexibility of choosing a name for your URL list. If you decide you want to open up a saved list of URLs again, you can import your list, and a tab for each URL will be allocated, opening the URL(s) in their corresponding tabs.
