Add "skin"-ing to design elements. A new desing element or resource can help to create the same look-and-feel for all elements. When You design several forms, pages, views, etc, it requires a lot of work to create the same look-and-feel. If the developer can assign some parameters to these elements it would make this work more easy. And can avoid hard work when customers want to chanege a simple coloring on all views and forms.....
Form backgrouns, labels, table header, cell, border, view columns, view header, action bar, buttons, links, etc.
Eg: there is a style element for view colums: name it to myCategoryStyle, set caracter, color, justification, etc...then assign it to all category columns in your app.
