But it's possible that your application does not use some of the included widgets at all. In my opinion it's better to build a core module which contains the basic stuff (which is already quite big) and than special modules for pages of the same type. As explained before maybe a package which contains all toolbar and menu classes. This means you have the same positive effect of caching the files, but you also reduce the initialization time. If you include less classes the application initialization is much faster in general. This time otherwise affects all you pages. Better to load a small feature module and have some modules with duplicated classes, than load too many classes in every single page.
