Brief Summary
One of the features that I miss most from safari when I switched to Orion is: open pages as tabs instead of windows option. The lack of this feature forces me to juggle between windows. This feature would smooth the work flow for users and using Safari's method of doing this wouldn't force this feature on the user.
Safari's Implementation:
With options of: Never, Automatically, and Always
Slightly unrelated: I noticed that Orion's built-in popup "blocker" failed all of these tests: https://webbrowsertools.com/popup-blocker/ and as a daily user, I am yet to see Orion's built-in popup blocker actually block anything.
