...That's been marked for translation in the next build.
In general by that you mean the phrase will also be added to the language file(s)?
If I understand the concept correctly once anything is "marked" it can be translated by putting the exact phrase at the very end of the language file, right? The problem is if translator adds it manually and later it is added as well by developers within the file where it belongs, duplicates are made, right?
Another complication is if translator is working on updated translation file but before it is finalized and delivered to developers, new updated language file(s) are released in latest build.
In other words it would be nice if we (translators) would know ahead when new updated language files are going to be released so we could deliver updates in time. End of month perhaps?
I hope I make sense and it's not confusing.
