When a message is deleted, it says 'Removed'. Unfortunately, this gets very annoying when I'm trying to edit multiple chat messages together into a single message that is more useful if it is starred, as there are 2-5 'removed' messages right under it.
It would be nice to find a better solution to the 'removed' message. Maybe the transcript could have the 'removed' bar, but in regular chat it would disappear eventually? I'm not sure exactly how to fix this, but it seems like the current implementation discourages reducing messages into single, better quality messages.
