Other notes I had:
-Connection rating can be displayed for every player inside a lobby. (Will be helpful to know who's connection is legit before doing a match)
-Icons displayed next to your name in Player Match rooms.
-Avatars have multiple color palettes.
-Plates have multiple color palettes.
-You can wait for online matches while playing Arcade, Training, VS, Tutorial, Challenge, Score Attack, and Unlimited Mars.
-Player Match settings can be edited while inside a room.
-Player Titles for your D-Card Profile is three slots, and a huge list of words like P4U.
-Can set what time you are available to play on your D-Card Profile.
-Icons and Plates don't seem to be a gacha system like Arcade. Looks to be like BBCSE gallery where you just pick a hidden one and purchase with P$.
