Let players use the blacklist function in duties.

Let people send /tells during duties.

For Yo-kai Medallium, add some kind of visual effect to signify that you've obtained the weapon for that minion. A check mark or sparkles is simple yet good enough.

Add some kind of 'dye box' to store your dye in permanently. Kind of like how Beastman tokens were converted from carry-able items, to currency. I have enough unique dyes, constantly on hand, to fill up basically 2 block of inventory space. That's 70/140 inventory space. You can fit I think 135 unique dyes if you have them all. Add a cap of 99 or 999 to the box if needed.

Ease up on the consent restrictions on Duty Recorder and make it available to more content. As a trade-off to lifting the consent restrictions, make all players' names invisible. Make names visible when all players consent. It would be very interesting to play Duty Recorder at the same level of 'Theater Mode' from Halo 3 or something. Except with the added features of lighting adjustments, sticker mode, and every other features available in /gpose. So much potential here for fun. Maybe this game is just not technically there yet?
