In DC, I frequently receive and also send long messages, when I read them, everything is fine, but every time I move through the messages and one of those messages of endless texts appears, it really is stressful waiting at the end of the message.
That’s why I suggest:
Collapse long messages, of more than 2 screens, once they have been read
Only the initial part of the messages could be displayed, occupying only half a screen, and in the lower region of the messages a button that allows it to be displayed completely
