I have often seen and heard mention of Oceania for a great number of the Pacific islands, often also including a few of the bigger ones.

Also Greenland as part of neither Americas nor Europe, but not too often.

And if Eurasafrica should be 3 continents with that massive land border between Asia and Europe, the "Indian subcontinent" should also be raised to be a full continent.

I am looking forward to what you make of it :-)
