The save button appears on feature pages.
It's colour remains the same before and after saving, hence the user does not have a clear indication that there are
-> Changes to save
-> That the save has been effective
-> When there is nothing to save : Render the save button in another colour (light grey)
-> When there is something to save : Render the save button in blue, as currently the case
I will test different saving across different features, including with different 'commit preferences'
