I did have some ideas which would have been helpful, but when I tried messaging MoYu, they said my suggested changes were going to be too expensive to implement, because they'd need to change the shape of their moulds. Qiyi just never replied.
I'd really love to see any updates or signs of further development. They've both said they were working on them ages ago but we've heard so little recently.
I don't think a petition will help very much (especially since you're only going for 100 signatures), but I look forward to seeing if it makes a difference anyway.
