When I click the (history) back button while holding Command, a new tab is opened with the previous page.
The new tab has no history now. You can't go back further in the new tab.
In Firefox the history from the original tab is copied to the new tab. I find this really useful sometimes and it would be nice to have this behaviour in Orion as well.
Another possibility (or additionally) to achieve the same, would be a feature to duplicate the current tab with its history.
