Does Support Equations and Code?

YES! Equations can be added directly using SGML-based notation for example

For example

C = Co e-kt H(s) = ∫0 e-st h(t) dt

A more modern mathjax plugin will also be included very soon.

Code blocks can be placed with regular text

By the way code blocks are supported with markdown (space over 4 then type code)
boy <- girl...

or even “inline” TVCL1=THETA(3)*((WT/70)**0.75)*(1+THETA(10)*(AGE-6.9)) in the middle of text.
