Henford-on-Bagley is a new ridiculously small world again

Imagine if they gave us the option to include or exclude certain worlds in our savefiles? Or link certain worlds together in groups, only having a small selection of them active and travel-able at a time. That would be nice.

Kind of like how TS3 makes us select which packs we want to use, through the launcher, because all of them at once was getting too unstable.
