Indeed, tested it ok and renamed files accordingly. Thanks Konstantin.
I was puzzled because Sutio generates the default localised field name (by parsing and splitting the field name) only if you click on the localisation icon for a field.
As a sidenote, that would be nice to have a way to make Studio generate automatically and systematically the default localised field name, instead of just in time when clicking on field localisation. For English, most of the time we won’t touch it, so it saves a lot of time.
