For example when reviewing long strings (_desc strings, for example) it can be quite straightforward to see which is outdated but fixing them may require some more time. Been able to mark strings as outdated would be helpful in that scenario, even more when you want to do this work collaboratively because in that way every translator could see which strings needs fixing.
Ok, thanks. May I ask for submitting that feature request into the Moodle Tracker (project MDLSITE, component lang.moodle.org). Please provide the description and the use cases there.
I can't promise it would be a priority but having it in the tracker will make it less likely to get forgotten.
Maybe 'Mark as need fixing' would be more appropriate as translations are already marked outdated by AMOS if the original string changes.
This function would also come handy when approving contributions. If during the review I notice some mistake, I need to change to 'edit mode' to fix the string and thus loose the color coding and diff information of the 'review mode'. Switching between them takes quite some time. If I could mark the strings, I could go and fix them all after finishing the review.
