images are more understandable that words:

current ui:
http://www.zensui.org/img/Inkscape-default.png

proposed ui:
http://www.zensui.org/img/Inkscape-clean.png

// note that:

This change is based on a pure 2Desktop not 3Desktop... ie: not Xgl with "not-necessary" effects...

Since a page is a container/box for information (in this case an image) and Inkscape uses standards (SVG, XML) it is apropiate that:
Inkscape uses a simplified W3C box model.

in the clean/proposed version of the ui (which is color-coded) the following new/changed paremeters are:

Background Color  = black
// Width = variable /* this can be 2 values, width and height ...but they're better as variables */
Border Color = green
Border Width = 2px (this paremeter is optional, or can be user-selected to Zero width)
Border Height = 2px
Box Color =  white
Box Width = 1000px // aka "page" width
Box Height = 700px // aka "page" height

favorite-most-used way-of-measure = pixel (...or milimeter, etc)

I know Java and some C++ so I can help with some code too...

any feedback about the User Interface/Interaction for the new milestone of Inkscape?
