Add an option to the settings to navigation to the previous tab you had opened after closing your current tab. The current behavior appears to navigate you back to the previous tab in your list. For situations like pinned tabs, this means that you may be navigated to another random tab in your list.
Example Use Case:
When reading on a news aggregator (like hacker news), I open a link in a new tab. Navigate to that tab. After finishing reading, I close that tab. I should be taken back to my previously opened tab.
If I navigate to a different tab in the middle of that flow, it could either return to that other tab, or perhaps return to the tab that the originating "open in new tab" request came from.
