We are not considering this feature for development at this time because there is already a Chrome browser add-in available. This means any user could leverage the Trados cloud solution to proof their files using this extension, much like one can with tools such as Grammarly or LanguageTool. In addition, a Word add-in is already available, which means that users could "export for external review" in Trados Studio and then review and proofread the translation in Word with this tool.
It’s also worth noting that we provide a well-developed API for Trados, allowing any developer to build this functionality if needed. Given the existing solutions and tools available, it's not something we plan to include in our backlog at this time.
