Better navigation on some of the pages

[andermat]

On most of the pages the return, save, cancel, create, etc. buttons are at the bottom of the page. It would be great if it could be located at the top and bottom or have a frame at the top that stays static and doesn't scroll with the page. Some pages have no buttons to return or cancel back to the previous screen making navigation painful. An example would be the data source list page when editing a device or the graph list page. Need to have consistency on all pages.
