well, up to you to decide if it's auser overload (at some point we need 
to stop and users should copy/patch setups ... that's the idea

concerning a title with commands ... no way around math in titles i 
guess (and tex math is sort of standard); we can think of having a 
"textitle" field, or abuse "title:en" for the formatted ones
