Richard, 

Since you are not the first asking these questions I feel I should write some 
documentation for the wiki. I'm still busy finishing my thesis, so here is a 
short description of what you will need:

- all parameters that are needed after startup of gnumed should be stored in 
the backend (you can as well store them in a config file, but that way your 
settings are only found on one machine)

- if you store them in the backend you can assign a user + workplace + cookie 
to identify the settings in which the value you stored will apply. Usual design 
is to hold data for one or more of 
        - current_user + current_workplace
        - default_user + current_workplace
        - current_user + default_workplace
        - default_user + default_workplace

  The cookie can be used to further refine the applicability of this value and 
might hold data like patient-id, day of week, etc.

- There are two convenience methods:
        1. gmCfg.getFirstMatchingDBSet, which will return the first appearance 
of the parameter in question, descending the above shown list of user/workplace 
pairs. 

        2. gmCfg.setDBParam, which will set the parameter for one 
user/workplace/cookie set to the specified value. If it didn't exist before, it 
will create this parameter for you in the backend. 

In order to do what you want, just call 
getFirstMatchingDBSet(option="Demographics.window.column.size") and it will 
return you the value you set for the current user (if nobody set default 
values). 
If you want to set the value after the user changed the column size, just call 
setDBParam(user=gmWhoAmI.get_db_account(),option="Demographics.window.column.size",
 value=newValue) to set the value for the current user and default workplace. 
A last word on how to name you config options: you can name your options any 
way you like. However, it should be somewhat self explaining. Note, too, that 
the Setup plugin will assume a hierarchy with branches denoted by dots (as in 
python namespaces). So "Demographics.window.column.size" and 
"Demographics.window.column.color" will show up in the same branch of the 
navigation tree. This leads to a easier navigation and cleaner appearance.

Hope this helps. If not, please tell me how I can help you.
