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 or Cmd 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. Note that OneTab is designed to leave in place any 'pinned' tabs you have.
You will not lose your list of tabs if you accidentally close the OneTab window, if your browser crashes, or if restart your computer.
February 2017 Update: We've been working like crazy to make OneTab much much better - including implementing lots of your feature suggestions. We're full time on it now and have great momentum. Thank you for all of your thoughtful feedback, please keep it coming.
