I'll give an example based on spanish translation for UserAdvManager plugin :

Before the use of the translation tool, to help translators to find easely what's left to do, I copied translation keys with english values from english reference file to other translation files like spanish one and I put a "/*TODO*/ prefix on front of each keys. Like this :

/*TODO*/$lang['UAM_Error_Using_illegal_flag'] = 'Syntax error ! The [Kdays] AutoText flag is used as the "Deadline for registration validation limited" option was not activated. Please activate the option or correct the text field(s) colored in red.';

Spanish translator knew this is to do, did the translation and removed the "/*TODO*/" prefix.


Now, in this case only, and if I understand how works the translation tool, it can't make a difference between translation done (without "/*TODO*/" prefix) and translation to do (with "/*TODO*/" prefix).

Should I remove all TODO prefixes already in place to make this work better?

Well, if it's better, I can remove all /*TODO*/ prefixes but should I remove non-translated values too ?
