Remove the Boxes around chat Text, it looks weird, let the text show up in a free flow format.
The boxes around the chat text typed is not needed or we should have an option to turn them ON or OFF.

Agreed, prefer the text be left aligned (option) and no box surrounding each message. Provide another feature that allow the person typing the message to have a colored name so it is easy to distinguish in channels what person typed the message. Slack has this functionality and it makes it very easy to read.
