To do this, you'll have to take out the media queries that hide the chat. Take out the hidden-xs accordingly in the header.tpl.
I hope this helps!
Edit last chat message by pressing arrow up key [ ↑ ]
Hey there NodeBB team,
The chat feature integrated into NodeBB is great. One feature which would improve usability and convenience a lot would be the ability to quickly edit your last sent message by pressing the arrow up key on your keyboard (while the cursor is focused in the text box below). The current workflow requires to leave your keyboard and do all this by mouse which is not the best UX for a chat solution / not that intuitive.
This would make correcting all these mall typos everyone does way faster
