Flaws in the BBCode 1.0 specification

I have noticed that people use [sub] where something like [small] was meant. The Shiichan implementation of BBCode 1.0 doesn't cover [small], which is kind of annoying.

We should design the 1.1 specs, since this effort looks like abandoned^[1]. Post all your proposals here. Particularly, IIRC, someone requested some LISP-like features. A formal description of such improvement would be nice.

I think that you are dropping some of the flexibility that BBCode provides. Try, for example, to write the following with your lithp:

[b][i][u][sub][code]BB[/sub]^Code[/u][/i][/b][/code]

Which should (if it's not a failure) render as:
