OneTab lets you easily export and import your tabs as a list of URLs. You can also create a web page from your list of tabs so that you can easily share your tabs with other people, other computers, or with your smartphone or tablet.
You can drag and drop tabs in your OneTab list to reorder them. You can also hold down the Ctrl key while restoring tabs and they will remain in your OneTab list (meaning you can use OneTab as a way of quickly launching a set of commonly used tabs). OneTab supports retina displays.
