Basicly, I think container's title object can use HTML editor instead of textarea control. This can let the container display better title for DNN. (currently, container title can display html also, but html will become the contain's name. This will become very strange when others want to reference the module's title.)

The menu's name & title are also have a lot of space to improvement. Expecially for the language other than English.

If the menu can display image menu or flash(currently can display icon plus text.But has problem when display image only), I think DNN will become more attractive to end users. Actually, I even thought DNN should let menu become a module to let user insert in the edit mode and can select it display mode. Maybe DNN can just extend links module to do it.
