Automatically save changes in map builder
One problem I keep running into with the map builder is that when I'm editing something on one of the individual property screens (style, location, markers, etc.), sometimes I'll accidentally click the save icon on the right-hand side instead of scrolling down and clicking that panel's save button. When I do this, it throws away my changes. It would be awesome if that right-hand save button would also save the data on the current property page... or at least warn me that I have unsaved changes before throwing the changes out.
