That is a nice idea/request.
But note that there are more calculations, especially if there are a lot of contents (like Angel's Warehouse) will cause massive lag. So I still have the current behaviour as default, the new "random scatters" are provided as options.
I have provided some options in my current test version (which may be published on Thursday, if everything works fine).
I have made some screenshots or how things look like, on FAQ page.
"Circular" options are more costly than "Square" options. "each Item" options are more costly than their "by Stack" options. So players not using modded large containers can choose the "better-looking" options.
Please comment on how you feel, and what may be improved.
If they are not good enough, I can add even more distribution options. Please provide mathematical formula (like, x = ..., y = ...) if there are any specific distributions you would like to see.
