Imagine a user is viewing map, screen or slide show. In order to change it, he then has to go back to the list, find it, edit it, got back to list again and then go back to view. This could be solved with an edit button in view mode. Maps could have a new button "Edit map" after dropdown which leads to map constructor. Screens could have a new button "Edit screen" after dropdown which leads to screen constructor. Slide shows could have a new button "Edit slide show" after dropdown which leads to slide show properties (since there is no constructor). The new edit buttons could be located between dropdown and full screen.
