I looked into the first question (Can I have a multicolumn list with no 
headers ?)

There is a parameter to pass into wxListCtrl, but there's no equivalent in 
PythonCard. We'd need to add a "heading" field to the resource, and then 
use it to control whether or not wx.LC_NO_HEADER was passed in to 
wx.ListCtrl.__init__

Note this is an initialization-time only setting, can't be changed once the 
list exists.

[ Kevin - I tried adding this as an extra parameter and found there's still 
some things I don't know about resources :-)
   I'll email you off-list about it .... ]

There's a cheap hack that I used to test how it might work - use the 
existence (or not) of columnheadings to determine whether or not the list 
should have headings. Not the right long term answer, but a quick easy way 
to get it if you need it soon ....
in components/multicolumnlist.py, at line 95, add

         if aResource.columnHeadings == []:
             rules |= wx.LC_NO_HEADER

so you will then  have
        if aResource.rules:
             rules = wx.LC_HRULES | wx.LC_VRULES
         else:
             rules = 0

         if aResource.columnHeadings == []:
             rules |= wx.LC_NO_HEADER

         self._rules = aResource.rules
          etc.
