I feel like some minor changes could be beneficial, like slightly darkening the red in PMs because it can be blinding to some people after long amounts of time. Overall, the UI is easy to navigate and quite lively though personally, I have experienced some issues with the swap feature. Sometimes it is a bit buggy, for example, I've had issues when swapping my account on the Phorum and trying to enter PMs, it logs me in on the account before I swapped, even if I log out and try again.
