Automatically save all open tabs in current window to the same directory..
This button will save all open tabs in the current window to a timestamped directory in your downloads folder, and then offer to close the window.
This is especially useful if you have many images open in their own tabs (for example, from using another one of my extensions, https://chrome.google.com/webstore/detail/open-all-imgur-pictures/dhajolcjglokhcbjkbbmembdlajcenon) and you want to save all of them.
Open Tabs lets you create groups of tabs, save them across multiple devices, and reopen later.
