Re: Re: [PATCH] Swixml - Extending DefaultFactory

I agree with Wolf - Swixml should focus on gui design, not on
replacing java code with xml. There are other projects which try to do
this. Swixml is small and fast - please keep it this way!
On the other hand, a plugin system for custom layouts, etc. would be
really nice ...
