Discretely leaving a group chat.

Others have made this point before, but I don't know why it hasn't been addressed. If someone leaves a server or closes out a DM, it doesn't send out a notification, but if you leave a personal group chat it does. I like to keep my conversation bar relatively tidy, so I close out of DMs that have been dead for a long time, but there's no way to close out without specifically leaving the group chat and notifying everyone.

This can be quite awkward, especially if there has been a social fall out since the group chat was active. There should be an option to either close out the conversation without leaving the group to reduce clutter in the conversation bar, or else a way to leave the group without notifying everyone.
