MamaOfWill, I know exactly what you mean. Isnt it just awesome to have courses all organized and put together?!
KL, would probably give a much better overview of what is in the works. But among other things, the new LR version that is soon to be released would have some great new functions, -- which would make it very easy to put courses together. You can check a brief overview here:

I also know that BK team is creating additional English curriculum categories to be released soon, and of course LMs!
I like your ideas of creating structured History / Geography / Science courses, I personally would love to have also Classical Education courses, -- like Classical Art appreciation, Bible/World Religions History, etc. I am sure if all of us suggest topics and ideas, they will be added to the "projects to tackle" list, and sooner or later they will become a reality!
