Yeah, and normal users will think our plugins using XML + chrome sound 
better. (Seriously!) This is not to be underestimated if we're 
interested in having normal users taking our stuff seriously.

Yeah. It would be cool with platform independent GUIs, constructed 
from only graphics, XML and (optionally) script code, but that's 
really a layer you would build on top of libxapgui, or as an 
alternative solution.

Either way, when it comes to libxapgui, I would prefer something that 
separates rendering from logic on the "widget" level. That is, 
instead of having a slider widget with a background image and a knob 
image, you'd have a slider widget that's supposed to be placed inside 
a suitable container widget, using another container widget as a 
knob. How about putting some tiny buttons inside that knob...? ;-)
