I've uploaded here what a view or browse mode should be (and what is currently).
I guess you could add an "edit" entry in the top right menu , that would lead to the edit mode, The edit mode could be the same as the current one, plus a "save" buton somewhere. Then of course you need to decide when to switch from edit to browse. To me, it should be as soon as you save or leave the edit window.
Hope that's clear enough.
