Alright, so I wanted to wait until I had more themes done, but I'm lazy and I'll only be working on them a little bit. Plus other people seem to want to contribute their emoji edits, so it's not just me adding these.
Each board theme has two changes, although any that I did not make myself will not
have both. The first is the default emojis. These are what you
see. They change depending on what your theme is.
Cat Theme (not every emoji is replaced):
If you want the emoji you use to be seen the same no matter what theme someone is using, you'll have to use one of these.
Not every emoji is accounted for, and as of right now there is no way to access every emoji this way, but in the future it might be expanded upon.
The second change, the one you won't see for some of the themes, is the change to the icon beside the boards.
To change your board theme, follow these steps.
1. Go to your edit profile screen.
2. Go to Edit Options.
3. Changing your board theme is in the bottom right.
And that's it! We'll try to keep you updated when additional themes are added, but feel free to pick one you like most.
