1. Ultrabullet and Racing Kings are considered as variants in one's profile, but don't appear as one in the menu. (The 3 bars next to one's name above.)
2. If you hover your mouse over one's name, the Ultrabullet rating is shown at the bottom part among other variants rather than the standart ones on the top. (Bullet/Blitz/Correspondence, etc.)
3. The Rapid and Classical symbols could be replaced with something better instead of the relatable animal puns. (The symbol shown for the shield arena announcements looks far more suiting for Classical, as an example.)
4. An option to change our main right-click arrow color. Not every board goes well with the green arrow, nor anyone needs to hold down a key on their keyboard all the time.
1 & 2 are errors that need to be fixed.
3 is a suggestion.
4 is a necessity.
