Secondly, you can now pin the chat in individual pages. This makes the chat stay visible even when the cursor leaves the chat area. Might be useful if there is an intense discussions going on, while you're also multitasking yourself.
Thirdly, you can create a personal list to links of, say, reaction faces that would be appended to the bottom of the chat. The idea is to be able to quickly respond to a post with an image of a reaction face. The list would be taken off this page: Special:MyPage/chatango (you need to have a Wikia account and be logged in). See mfaizsyahmi's example.
This change would bring about some changes, chiefly improved privacy and reduction of anons that would otherwise be visible in the chat, and might take some time getting used to for seasoned wiki visitors. Rest assured, it's all for the greater good.
