I didn't see that forum. I often forget the technical term of what I am looking up. I was looking for sprite images instead of spritesheet... I change the title to spritesheet and removed sprite images. I will however leave sprite images in the post a few times as a tag. Thanks for the time. I will post the answer here so others don't have to look through and read it all.

"An upcoming release groups objects on to spritesheets according to those which are used together on layouts, which is aimed at solving exactly this. However with a couple of projects I tested, it didn't seem to make a big difference to memory usage, which I think indicates it's not a major problem.
I don't think Kiwi Story is a very good example, because it's pretty tiny in terms of memory usage - only around 20mb or so. This is small enough that it's probably better to group as much as possible on to the fewest number of spritesheets, to get the maximum performance. It's only really important for scalability, when you have games which use hundreds of megabytes of image memory."
