2 years ago You can see the graphics changed in real time, so it should be clear which can be used and which cannot. Since someone might want to change a graphic set to be "Plains 3" or whatever, I would still leave the option there.
You cannot easily change the graphic set of a level, only if the graphic sets are compatible. If you want level 1-1 to be a hilly level, the advice has been to use another level, like 1-2, and swap it with level 1-1.
That does make the graphic set setting in the Level Header Editor redundant and also confusing for newcomers.
