What does your feature entail? What is it for? How will it affect existing workflows or user experience?
Safari for iOS offers an easy way to select a tab that was closed recently (not necessarily the last one), via a long press on the plus (+) button. Especially handy when you don't remember when you closed the tab (no need to undo multiple tab close actions to find it).
This would also add another option to discover how to undo compared to "shake to undo", which seems to be the only way of undoing a closed tab in Orion right now (and only the most recent one).
What are the exact ways that you see a user using your proposed feature? Please go into as much detail as possible, and provide examples of how other browsers/apps implement this feature, if applicable. If your feature suggestion adds on to an existing feature, how would it work into it to extend its usefulness?
