woah check out this pool and how it handles chapters:
pool #33074

how long has the syntax used to make that layout been there? gimmie a piece of that!

I believe TsukiLeaf is probably the main (if not only) person behind formatting pool chapters like that.
The syntax has ostensibly been available over 7 years ago (or 4 years if you only count when the formatting wasn't broken on the wiki), since it uses tables to format it that way.
