A nice feature of Dubtrack is the ability to use DubX, an extension that adds plenty of fun options, from using twitch emotes to auto-fill mentions and even custom CSS.
One of the options is to use the community CSS, which will be really great once we make a nice looking CSS for the room.

In order to use DubX you need to do some actions depends on your browser, the easiest way; By using this method, Dubtrack will activate DubX once you get into the site, without needing to do anything.

After having DubX activated, there should be a settings button in the same bar your name is in:
 

The rightmost button.

To use the community CSS, tick the "Community Theme" option under the "Customize" section.

Other options I recommend are:

Emotes - Twitch, and other sites emotes.
Autocomplete Emoji - To be able to use the emotes without super memory, type `:` (colon) and a list of emotes will pop up.
Autocomplete Mentions - Similar to how Discord mentions work, when you'll start typing a mention it will give you a list, making life easier.

Split Chat - creates shadings to distinguish between different people in the chat.


If you have any questions, I'll be glad to answer here and in Discord.
PS. Snow option is lovely.
