Hi Shaheem,
KonaKart uses the Struts and Tiles frameworks. The order in which the boxes are displayed (and whether they are displayed or not) is defined in WEB-INF\tiles-defs.xml . The JSP which lays out the tiles is called MainLayout.jsp. By looking at this JSP you can see that the tiles are positioned in 3 columns. You can modify the JSP to layout the tiles any way you want. If you want to change the width of the tiles you just need to modify the line where you see <td width="125" valign="top">.
Hope this helps.
Paolo
