	Agreed. After playing around with all the various sizer options in  
wxPython, we settled on just that combination: dSizer is based on the  
wx.BoxSizer, and dGridSizer is based on wx.GridBagSizer. That seems  
to cover any layout situation I've come across.

	If it saves you some effort, I went through the same effort with the  
Dabo Class Designer. I started with a PythonCard-like approach, with  
objects that used absolute positioning, and then tried to add sizers  
into that mix. It was impossible to visually represent that mix of  
sizer and non-sizer layouts together.

	The only approach that seemed to be feasible was to go with the  
sizers-only design, in which you create the sizers and allocate  
'slots' that then get filled with controls. I have a couple of  
screencasts that show this approach in action, and also try to  
educate people who are new to sizers how to approach laying out a  
form; perhaps they might be helpful to your ideas on adding sizers to  
PythonCard.
