I thought it was just a "me" thing, but I hate (emphasis added intentionally) the "Enter to Send" option for replies (Direct Messages, Thread Replies, Blog Comments).
But... there's been a request made by a few in our community to also disable it, so I decided to reach out. I couldn't find something specifically in the documentation (Manager Trailing or Developer Training), but I might be looking for the wrong terms to find the information.
If anyone has done this, please, please, please let me know. I think it would simplify the experience with our members.
