With regards to the new UI

I don't like it.

The simple fact that inactive messages (ones that your mouse is not over) are brighter than active messages (the message that your mouse is over) is very disorienting, to say the least. Please, either

-change it back to what it was before the update (recommended)

OR

-reverse the colors: Make the inactive messages darker than the active messages

ALSO, with the new update, I can no longer edit/delete/react to messages while on my MacBook 2008 (using Chrome) , as it only shows one emoji (heck, one I've maybe used once, :100:) and nothing else.
