Improve the chat UI to make messages sent to sent by sender, such as using different background colors, dividers, or left/right alignment. Currently, message boundaries are concerned, missed users to miss parts of messages, especially in longer discussions. Significant separation would improve readability and usability. In the chat/message function, I would like UI improvements due to differences in background colors, dividing lines, left and right arrangement, etc. so that the breaks for each speaker can be easily understood. Currently, it is difficult to understand the speaker's breaks, and parts of the message may be missed, especially in the case of long sentences, so I would like to improve readability and operability.
