Button states: shouldn’t Publish changes be gray/inactive because no changes have been made to publish yet?
Update: new intended behavior per Matthias:
Basically: whenever you have any input that has *changed*, the button will become active & you'll be able to submit it.
Incomplete input (e.g. added a row, selected a language, but no content) is just ignored: if that's the only change, submit button will still be disabled - if there's another change, submit will be enabled, but the incomplete row won't be submitted.
