This is actually a theme-specific revision, not a core change. I'd suggest opening an issue at https://github.com/nodebb/nodebb-theme-persona/issues and detailing the necessary changes there. Thanks.
SEND button next to CLOSE button in chat

... is definitely a bug. Did not happen for the first time that I clicked CLOSE instead of SEND. Especially because the color is so much more attractive. Please move the CLOSE button somewhere else.
To be honest I think the close button should move next to the maximize button. @baris, what do you think?
