Currently, the WE allows translators to add comments at segment level, however those comments aren't made present during the translation.
It would be good if the translator had an option to raise certain queries / comments from within the WE, that get routed to the PM. As a basic feature, this would basically report and prompt the PM when the translator raises something from the web editor. Taking it further would be more query management - a database at project and customer level for raising queries, sending to be checked and provided answers.
