Even if it was an unused feature in the official forums, it still existed, some Xenforo based forums use it like https://forums.terraria.org (scroll all the way down and you will see a theme selector, default is underground).
But lets forget about Xenforo, is it possible to have a similar option in these forums? if yes, can we expect to get one in the future? it doesn’t have to be too complex, just some color changes and different background. if no, can we at least expect background rotations sometimes?.
Is not that i dislike the current one, in fact these forums looks beautiful and modern compared to others i have seen so far, but i appreciate customization, something that VG forums didn’t include and i had to stick with the boring black and white interface for 2 years.
