By the way, I just realised I never got around to posting an update on this.

These are done. Number 2, as evident from the link
bbbird shared with us.
As for 3 and 4, you can now type continents into the origin/destination text boxes
e.g. Europe, Asia, Oceania, Africa, or North/South America (traditional chinese characters supported as well) to filter for airports by continents.
You can also type the airline code, e.g. JL, AA, CX to filter destinations by serviced airlines.
