When I reopen Orion I often have to close more than one unused tab in the tab bar. It got me thinking why that happens?
I noticed that often I click new when there is already a unused tab open. Call me stupid by doing that, but why not first use the already open unused tab when a user clicks 'new' instead of creating a new one?
Alternatively add an option in Settings to remove new unused open tabs when Orion is quit. It will provide for a cleaner experience.
I might be overlooking something so please chime in if there are scenarios where you would want to have multiple unused open tabs.

When a use clicks the new tab button (or presses shortcut to do so) Orion first checks if there is already a unused new tab open that is not active at the moment.
If this is the case it will activate that unused tab instead of opening a new one.
If the user has the unused tab active when clicking the 'new tab' button Orion creates a new tab.
