I think this is useful gmap. however, i have some suggestion for that version. if you could write an app for N900 that would be awesome. because running on browser is painful. the navigations buttons seem small and not respondsive sometime, hard to see, the arrow sign isnt standout. zooming button is overlap with gmap defalut clock wheel. should include bigger rotation button to avoide using n900 stylus. address search box should be larger for easy viewing, at lease 75% of total screen, 3 functions button should be redesign, cos i really have no idea what the other two represent until i click on it.

overall thanks for your good idea.
