I think you've got a point there, SS. I figured that the individual major landmasses would have their own names under the continent name anyways, so let's shelve the continent discussion for now and move on to those major landmasses, I believe we'll have much more progress there for the time being. I've made an image that lists every major landmass.
That is here:
