Some common logic that is used:

• the Translation in Sync and Translate From Language fields are never shown for primary language
• the Source ... fields always show value (and have that language in title) from translation source language (if non set will fallback to primary)
• each phrase have it's own translation state
• saving phrase (even without translation change) would make it in sync automatically
• saving as primary would force other translation of same phrase to look back into that language for original translation (during editing only, no effect when phrases are used on other pages)
